Question

The lateral surface area of a cube is 324 CM square find its volume and the total surface area

Answer 1

Answer:

729cm^3

Step-by-step explanation:

4a^2=324

a^2=324/4

a^2=81

a=9

volume =a^3

=9^3

=729cm^3

Answer 2

Answer:

L.S.A of a cube= 324cm^2

Also,

L.S.A of a cube= 4a^2

So from equation 1 and 2,

L.S.A of a cube=4a^2 = 324

a^2 = 324/4

Therefore, a = 81cm

T.S.A of a cube = 6a^2

= 6×81^2

= 6561cm^2

Hope it helps!!
