Question

surface of a cube is 1176 CM square find its volume

Answer 1

We know that surface area of a cube = 6a^2.

Given that surface area of the cube = 1176.

6a^2 = 1176

a^2 = 1176/6

a^2 = 196

$a = \sqrt{196}$

a = 14.


We know that volume of the cube = a^3

                                                          = 14 * 14 * 14

                                                          = 2744cm^3.


Hope this helps!

Answer 2

T.S.A=1176 CM
T.S.A OF A CUBE=6L^2
⇒1176=6L^2
⇒L^2=1176/6
⇒L^2=196
⇒L=√196
⇒L=14 CM

∴VOLUME=L^3
=14^3
=2744 CU. CM
