what is the formula for the surface area of a rectangular prism?

anonymous · Answer

SA = LA + 2B?

anonymous · Answer

surface area = length X area + 2 X base?  now I am confused.

anonymous · Answer

SA = lateral area + 2 x base?

anonymous · Answer

Is that not the formula used for any prism to find its surface area?

anonymous · Answer

ok, Yahoo says it is Area = 2 ( WH + LW + LH)  where W is width    L is length    H is height

anonymous · Answer

so let's look at one that is 4x4x4   what is its surface area?

anonymous · Answer

L = 4, W = 4, H = 4    can you solve for Area?

anonymous · Answer

Area is length times width, so, 16...

anonymous · Answer

that is the area of one side of the box, but there are 5 more sides to deal with

anonymous · Answer

area is 2 ( W*H + L*W + L*H) for these boxes
