Question

Find the edge of a cube whose surface area is 432 m square

Answer 1

GIVEN : Surface area of cube (S.A) = 432m²

To find: edge of cube (l) =?

Formula : S.A = 6 l²

432= 6 l²

432÷6=l²

72=l²

Taking square root

l = √72

l = √4×18

l = 2√ 18

l= 2√ 9×2

l = 2×3 √ 2

l = 6√2 m

Answer ~ the edge of cube is 6√2 m

Answer 2

Answer:

Hey here is your answer!!!

To find the side just use the formula of surface area of cube i.e

Surface area of cube = 6a^2

432/6 = a^2

72 = a^2

a= √72

a= 6√2 m
