Find the surface area of this rectangular prism l= 15mm, w= 3mm, and h = 4mm

The correct answer is: 

Explanation:

First convert l, w and h in meters:
l = length = 0.015m
w = width = 3*10^-3 m
h = height = 4*10^-3 m

The surface area of rectangular prism = 2(wl + hl + hw) = 2(3×10^-3 * 0.015 + 4×10^-3 * 0.015 + 4×10^-3 * 3×10^-3) =

The answer is mathg.a.y
