For this question, we need to use the formula for getting the surface area of a rectagular prism which is:
A = 2 (wl + hl + hw)
A = Area
w = width
l = length
h = height
According to the given,
w = 7.6
l = 9.4
h = 4.8
Now, using the formula stated above,
A = 2 (wl + hl + hw)
A = 2 [(7.6)(9.4) + (4.8)(9.4) + (4.8)(7.6)]
A = 306.08
The answer would be 306.08 cube inches.
