The correct answer is: [tex]2.34*10^{-4} m^2[/tex]
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) = [tex]2.34*10^{-4} m^2[/tex]
