I got X=11

Minus 7x on both sides
The equation the becomes :
-2x +179=157
Subtract 179 from both sides
Equation now is:
-2x= -22
Divide -2 on both sides
X= 11

The volume of a cube is 27 cubic meters. what is its surface area in square meters?

erma4kov [3.2K]

To find the answer, take the measurement of an edge of the cube, multiply it by 6, and then square that number.

Ex:

Edge = 16

Faces in 1 cube = 6

6 * 16 = 96

96^2 (which is just 96 * 96)= 9,216

I hope this helps! :)
