If the volume of a prism is 999 square inches what is the volume of a pyramid with the same base?
If the VOLUME is 999 SQUARE inches then you have gone wrong. SQUARE inches are a measure of AREA VOLUME is measured in CUBIC units. Assuming you meant The volume of a prism is 999 CUBIC inches, then the volume of a pyramid with the same height is indeterminate (cannot be given), as there is NO INDICATION of how the height of the pyramid relates to the height of the prism. So, ASSUMING you mean the volume of a prism is 999 CUBIC inches AND the HEIGHT of the pyramid is the same as the height of the prism, then the volume of the pyramid is one third that of the prism, ie 999 cu in ÷ 3 = 333 CUBIC inches.
How do you find the volume of a frustum?
If it is the frustum of a pyramid: The volume of a pyramid (with a square base) is: Length_of_base * Width_of_base * Height * 1/3 To get the volume of the frustum, subtract the volume of the top part (also a pyramid) from the full volume. <><><><> frustum of a cone the formula is (h*pi)/3*(r1^2+r2^2+r1*r2) this is where h = height r1= top radius r2=bottom radius
How do you find the formula for the radius of a cone?
There are many ways you can find the radius of a cone. The simplest way is to divide the diameter by 2. You can also find the radius of a cone if you know its volume and height. V = (1/3)(π)(r2)(h); V is the volume, π is pi (3.14), r is radius, h is height (3V)/(πh) = r2 r = square root of [(3V)/(πh)] You can also find it if you know the area of the circular base of the cone. A = πr2; A = Area, π = pi (3.14), r = radius r2 = A/π r = square root of (A/π) If you know the height and the slant height (also the hypotenuse) of the cone, then you can find the radius that way. h2 + r2 = z2; h = height, r = radius, z = slant height r2 = z2 - h2 r = square root of (z2 - h2)
What do you call a triangular pyramid with the top cut off?
A frustum. Specifically, a frustum of a triangular pyramid -- as one could also have a frustum of a cone, square pyramid, etc.
How many triangular faces does a triangular pyramid have?
a triangular pyramid has 4 triangular sides
When you see a picture of a right pyramid with a regular polygon base how do you identify its height and its slant height?
Its vertical height is that of the perpendicular from the centre of the base to the apex; the slant height is the length of the sloping "corner" between two faces. The height of a regular pyramid is the vertical distance from the center of base to the top and is usually shown with a line perpendicular to the base, denoted with a right angle to the base. The slant height it the height of the lateral face (the triangles) from the edge of the base to the top of the pyramid. It is the height of the triangle, not the pyramid itself. The slant height will also be the hypotenuse of a right angle formed from the altitude of the pyramid and the distance from the center of the base to the edge.
How do you find lateral area of a pyramid?
If it is a regular pyramid you need to find out the base perimeter, multiply it by the height of the sides (when considered as triangles) and divide by two. The height of the side can be found using Pythagoras's formula if you know the height of the pyramid and the length of a side. The side height of a pyramid is also known as the slanted height or L in a formula. Formula:permiter of base x L(side height) ( P of B)(L) p x L(slant) ----------------------------------------- = --------------------- 2 2 Good luck!
Find the surface area of the pyramid. The side lengths of the base are equal?
A pyramid is a generic term used to describe a polyhedron with a polygonal base and triangles rising from that base to meet at an apex. The polygonal base can have any number, n, of sides, provided that n>2. There is, therefore, no information about the number of lateral faces in the pyramid. Also, the surface area of a pyramid depends on its height and there is no information whatsoever about its height. It is, therefore, impossible to answer such an underspecified question.
How do you type in computer the symbol for slant height?
Unfortunately, how to type the slant height symbol is widely unknown. Here is one you can copy and paste. ℓ You could also save it into a .txt or .rtf file for later use.
What is the real name of the Great Pyramid?
the real name of the great pyramid is the pyramid of KHUFU. It is also the biggest pyramid in all of Egypt with a height of 441 feet!
How do you work out the trigonometry of a rectangular based pyramid?
The answer depends on what you wish to work out: the angles, height, surface area, volume. Also, you need more information: the vertical or inclined height and whether or not the pyramid is a right pyramid.
What is the surface area of a right cone with a base of 8 and a height of 15?
It depends on whether the base radius is 8 units or base diameter. It also depends on whether the height is the vertical or the slant height.
What has one triangular base and three triangular lateral faces?
That object would be called a triangular pyramid, also known as a tetrahedron.
How do you find the lateral area of a cone?
LA= 1/2(l*B)where "LA" is lateral area, "l" is lateral height and "B" is the perimeter of the baseMore info:B- otherwise (in a cone) known as 2Ï€r. 2Ï€r is also known as DÏ€ where "D" is diameter
What is the meaning of circular pyramid or cone?
A pyramid has a shape at the base (it can be turned, remember) and this shape becomes progressively smaller as its height increases to finally become a point at the top.The type of pyramid depends on the actual shape of the base. Some pyramids have other names also (eg a triangular pyramid is also a tetrahedron).A circular pyramid is also called a cone.The pyramids in Egypt are square pyramids.
How many faces has an octagonal pyramid?
An octagonal pyramid has nine faces. It also has nine vertices and 16 edges. You can find the volume of this pyramid by using the formula that the base 'B' multiplied by the height 'h' must be divided by three.
What was the height of the pyramid?
480feetThe tallest pyramid in the world is the Great Pyramid of Giza (also known as the Pyramid of Khufu and the Pyramid of Cheops), in Egypt. It has a height of 480.6 feet (146.5 meters).The largest pyramid by volume is the Cholula Pyramid in Pueblo, Mexico. It sits on a base over five times larger than the Great Pyramid of Giza.
