Step-by-step explanation:
The surface area of the box is <u>1048 square inches</u>
<h3>How to calculate the total surface area of the box</h3>
The formula for calculating the surface area of the prism is expressed as:
Surface area = 2(lw + wh +lh)
Given the following
l = 20in
w = 8in
h = 13in
Substitute the given parameters'
Surface area = 2(lw + wh +lh)
Surface area = 2(20(8) + 8(13) +20(13))
Surface area = 2(160+104+260)
Surface area = 1048 square inches
Hence surface area of the box is <u>1048 square inches</u>
