Question

HHHHHUUUUURRRRRYYYYY!!!!!What is the surface area of a cube that has a side length of 2.2 meters?

Use the formula SA=6s^2, where SA is the surface area of the cube and s is the length of each side.

A. 13.2 m^2
B. 26.4 m^2
C. 29.04 m^2
D. 174.24 m^2

Answer 1

29.04

I'm doing the quiz lol

Answer 2

Okay, so cubes have all equal side lengths, meaning that every side is 2.2 meters.
Since we already have an equation, let's plug the side length in for s, which represents side. The equation says that the surface area is equal to 6 of the side areas (since area = side^2).

SA = 6s^2
SA = 6(2.2)^2 exponents first
SA = 6(4.84)
SA = 29.04 m^2

Looks like C is the correct answer.
