Question

The surface area of a cube is 302.46 m^2. The length of each side of the cube = ______ m.

7.1
50.4
6.7


plz help thanx

Answer 1

7.1 m

Explanation:

A cube has 6 congruent square faces.

Given the surface area = 302.46 m² then the area of one face is

302.46 ÷ 6 = 50.41 m²

The area of a square = s² ( s is the side length ), thus

s² = 50.41 ( take the square root of both sides )

s =
`√(50.41)` = 7.1 m

The length of each side of the cube is 7.1 m
