Question

The lateral surface area of a cuboid with length 9 cm, breadth 4 cm and height 8 cm is.

• A. 208 $c{m}^2$
• B. 108 $c{m}^2$
• C. 204 $c{m}^2$
• D. 208 $c{m}^2$

Answer 1

Answer: (B), (D)

The correct options are
B 108 $c{m}^2$
D 208 $c{m}^2$

Given: Length $\left(l\right)$ = 9 cm, Breadth $\left(b\right)$ = 4 cm and Height $\left(h\right)$ = 8 cm

Lateral surface area of a cuboid is given by
$2\times (h\times l+b\times h)$,
where l, b and h represent the length, breadth and height of the cuboid respectively.
$\therefore$ Lateral surface area of a cuboid
= $2\times (h\times l+b\times h)$
= $2\times (8\times 9+4\times 8)$
= $2\times (72+32)$
= $2\times 104$
= 208 $c{m}^2$
