Answer:
The surface area of the rectangular prism is 124in³
Step-by-step explanation:
To calculate the surface area of a rectangular prism we have to use the following formula:
a = area
w = width = 1in
l = length = 6in
h = height = 8in
A = 2wl + 2lh + 2hw
we replace the values that we know
a = 2 * 1in * 6in + 2 * 6in * 8in + 2 * 8in * 1in
a = 12in ² + 96in ² + 16in ²
a = 124in³
The surface area of the rectangular prism is 124in³
