Question

The volume of a cube is 2744 $c{m}^3$. Its surface area is

(a) 196 $c{m}^2$ (b) 1176 $c{m}^2$ (c) 784 $c{m}^2$ (d) 588 $c{m}^2$

Answer 1

Given: Volume of the cube = 2744 \(cm^3 \)
$a^3=2744$
Hence a =
Side of the cube (a) = 14cm.
Surface Area of cube = TSA = 6$a^2$
= 6 x $a^2$
= 6 x ${14}^2$
= 6 x 196
= 1176 $c{m}^2$
option b is correct
