ANSWER
67 square units
EXPLANATION
We want to find the surface area of the right rectangular prism given.
To do that, we use the formula:
SA = 2(lw + wh + lh)
where l = length
w = width
h = height
From the figure:
l = 5 units
w = 4 units
h = 1.5 units
Therefore, the surface area is:
SA = 2(5*4 + 4*1.5 + 5*1.5)
SA = 2(20 + 6 + 7.5) = 2(33.5)
=> SA = 67 square units
That is the surface area.
