Question

3.If the volume of a cube is 216cm3 then
find its T.S.A, C.S.A

Answer 1

Answer:

TSA = 216 cm2 ; CSA = 144 cm2

Step-by-step explanation:

Volume= 216 cm2

Volume of cube = a x a x a

Therefore, a x a x a = 216

a3=216

a= cube root of 216

a = 6

TSA = 6a2

TSA = 6 x (6)2

TSA = 6 x 36

TSA = 216 cm2

CSA = 4a2

CSA = 4 x (6)2

CSA = 4 x 36

CSA = 144 cm2
