Question

Find the surface area of a prism.

Answer 1

Hint:

Step 1:Find the surface area of the prism.

The surface area of the prism is $=\left(2\times \frac{1}{2}\times 8\times 15+20\times 17+8\times 20+15\times 20\right)m^2$

$=(120+340+160+300)m^2$

$=920m^2$

Hence,surface area of the prism is $920m^2$
