if 3x4 is dimension of rectangle and 5 is the altitude, then, 49.035 sq. units is its surface area
the defnition of find the surface area of triangular prism and cylinder
Rectangle
To calculate the surface area of the equilateral triangular-based prism, you need to calculate the area of the equilateral triangle and all the other sides of the prism. The total area of all the phases will give the total surface are of an equilateral triangular based prism.
To find the surface area of an equilateral triangular prism you take the area of the rectangular sides and the triangular bases and add them up and your done.
There is no "height" of a rectangle, unless it's a rectangular prism. Do you mean the length? If you have the area of the rectangle, the equation should be:A= L x WPlug in the area and the length and solve for the width, or plug in the area the width of the rectangle, and solve for the length.
It depends on the size of the triangular prism, but depending on the side of the prism you use the triangle area formula to find it or the rectangle area formula to find it.
if 3x4 is dimension of rectangle and 5 is the altitude, then, 49.035 sq. units is its surface area
Three: 1) The area of the cross-sectional rectangle end 2) The area of the rectangle joining the longer side of the cross-sectional rectangular ends 3) The area of the rectangle joining the shorter side of the cross-sectional rectangular ends Then the surface area of the rectangular prism is twice the sum of these three areas.
The base of a rectangular prism is a rectangle. The area of a rectangle is length times width.
First find the area of the top triangle. Multiply that by 2. Then, find the the area of one of the side triangles. Multiply that by 3. Add both numbers and remember to but a 2 on the upper left of the total.
The cross-section of a prism is the same - it is the same as the shape of the two parallel "bases"; this cross-section can be any shape, not necessarily a rectangle. Each side of a prism is rectangular, so knowing the formula for a rectangle will help you along to finding the surface area of the prism by helping you to calculate the area of the sides; however, you will still need to be able to calculate the area of the bases (unless it is given to you), for which knowing the area of a rectangle may not (usually will not) help.
find the area of triangles(reflecting surfaces) and also the area of rectangle or square(base)and find the sum of both.
Volume of a rectangular prism= LengthXWidthXHeight Area of a Rectangle= LengthXWidth Area of a Trapezoid= (Bottom+Top)/2)XHeight
it is when you for example==== surface area = 2(6)(4) + 2(6)(3) + 2(4)(3) = 108 in. square surface area of a solid is the sum of the areas of the outside surfaces of a solid
If the base is a rectangle, use the formula for the area of a rectangle.
The surface area of a cylinder prism has round shape and the surface of a rectangular prism has a square shape.
