Question

find a side of a cube whose surface area is 432 m?

Answer 1

Hey dear 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


Hope it helps u dear...☺️☺️☺️

Answer 2

$\textbf{Solution :}$
__________

Let the side of cube be x meters

Surface Area of given cube = 432 m²

A.T.Q. [According to question]

[Surface area of cube = 432m²]

6 × x² = 432

=> x² = 432/6

=> x² = 72

=> x = √72

=> x = 8.48 [approx.]

•°• The side of cube is 8.48 m
