Question

A cuboid of dimensions 18.5 cm x 12.5 cm x 10 cm needs to be painted all over. Find the area to be painted.

• A. $$1157.5 cm^2$$
• B. $$1198 cm^2$$
• C. $$984.56cm^2$$
• D. $$1082.5cm^2$$

Answer 1

Answer:

$$1082.5cm^2$$

area to be painted $=2( 18.5\times{12.5}+12.5\times{10}+10\times{18.5})$

$=2(231.25+125+185)$

$=2\times{541.25}$

$=1082.5cm^2$
