find surface area of a prism

Question

H=9 L=8 B=16

Answer 1

To find the surface area of a prism, we need to add up the areas of all the faces.

A rectangular prism has two congruent rectangular bases and four rectangular lateral faces. The formula for the surface area of a rectangular prism is:

Surface Area = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the prism.

Given that H=9, L=8, and B=16, we can plug these values into the formula and get:

Surface Area = 2(8 x 16) + 2(8 x 9) + 2(9 x 16)
Surface Area = 256 + 144 + 288
Surface Area = 688

Therefore, the surface area of the prism is 688 square units.
