Question

A cube has a lateral area of 676 square feet. What is the side length of the cube?

Answer 1

Cube has 4 lateral faces
4s² = 676 = 4 × 169
s² = 169
s = 13
your answer is 13

Answer 2

Answer: Side length of the cube is 13 feet.

Explanation:

Since we have given that

Lateral area of a cube = 676 square feet

As we know the formula for "Lateral surface area":

`L=4side^2\\\\676=4a^2\\\\(676)/(4)=a^2\\\\169=a^2\\\\√(169)=a\\\\13=a`

Hence, Side length of the cube is 13 feet.
