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.

How do you solve the surface area of a rectangle prism?

Area of a rectangular prism = 2lw + 2lh + 2wh, where l is length, w is width, and h is height.


How do you found the height of rectangle?

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.


What is the surface area of one side of a triangular prism?

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.


What is the surface area of a rectangular prism with the dimensions of 3x4x5?

if 3x4 is dimension of rectangle and 5 is the altitude, then, 49.035 sq. units is its surface area


How many areas do you need to know to get the surface area of a rectangular prism?

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.


How do you find the answer of the base area of a rectangular prism?

The base of a rectangular prism is a rectangle. The area of a rectangle is length times width.


How can knowing the formula for the area of a rectangle help you find the surface area of a prism?

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.


How do you figure out the surface area of a triangular prism?

find the area of triangles(reflecting surfaces) and also the area of rectangle or square(base)and find the sum of both.
