Question

Cubic bins with closed tops are used to transport melons to the farmers market. The edge length of each bin is 1.5 m. What is the surface area of the outside of one of the bins
A. 3.375
B. 9
C. 11.25
D. 13.5

Answer 1

We know, Surface area of a Cube = 6a²
Here, Edge length(a) = 1.5

Substitute the value, 
s = 6(1.5)²
s = 6 * 2.25
s = 13.5

In short, Your Answer would be Option D

Hope this helps!
