Question

A Cuboid has length, breadth and height of 9 cm, 3 cm and 2 cm respectively. Find the total surface area of Cuboid.

• A. 102 cm${}^2$
• B. 51 cm${}^2$
• C. 132 cm${}^2$
• D. 145 cm${}^2$

Answer 1

The correct option is A 102 cm${}^2$

Given,
Length (l) = 9 cm
Breadth (b) = 3 cm
Height (h) = 2 cm

The total surface area of Cuboid = 2(lb+bh+lh)
$=2(9\times 3+3\times 2+9\times 2)$
$=2\times (27+6+18)$
$=2\times 51$
= 102 cm${}^2$
