Why is there a 2 in each part of the surface area formula for a rectangular prism?
For each side of a rectangular prism there is an opposite side that is identical in measurement. So there are two width sides, two length sides, and two height sides.
What is rectangular prims?
a rectangular prisim is part of geometry, its shape is like a tissue box
How do you find the area of a regular pyramid?
For a regular pyramid, the surface area (SA) is the following: SA= Area of Base + 1/2 [Perimeter x Side Length] As you know, the area of the base is the flat part of the pyramid which points the vertical lines to one point: above the center of the base. You need to find the perimeter of the base first, and then find the side length via Pythagorean Theorem (a^2 + b^2 = c^2). Finally, plug them into the equation above, and you'll have your answer.
How many faces on a quadrilateral pyramid?
It has 5 faces. The "quadrilateral" part of the name describes the shape of the base of the pyramid. A pyramid has 1 face for every side of the base plus an extra one for the base. Thus a quadrilateral pyramid has a quadrilateral or 4 sided shape for the base and so has 4 + 1 = 5 faces.
A 30-inch segment is cut into two parts whose lengths have the ratio 3 to 5 Find the length of each part Does anyone know how to figure this out?
Divide 30 by 8 (5+3). Multiply the answer by 3 for the one part length and 5 for the other part length.
