Question

Find the lateral surface area of the rectangular prism shown in the figure given below.

• A. $180c{m}^2$
• B. $200c{m}^2$
• C. $220c{m}^2$
• D. $2400c{m}^2$

Answer 1

The correct option is A $180c{m}^2$

Let's label the given figure.

Lateral surfaces of the prism:
ADGH, BCEF, ABFH, and DCEG

Hence, lateral surface area of the prism
$=5\times 10+5\times 10+4\times 10+4\times 10=50+50+40+40=180c{m}^2$
