Answer:
Of all 6 faces it would be 150
Step-by-step explanation:
If one side of the cube is 5cm long, then l × w = area of a face, so if it is a cube then all 4 sides are the same on a face so 5 × 5 = 25, so 25 × 6 faces = 150
10 to the exponent 2 is equal to 100, so 8.7 x 100 is equal to 870
L+L+(L-4)+(L-4)=72
4L-8=72
4L=80
L= 20
so W= 20-4 or 16
