Answer:
F
Step-by-step explanation:
1m = 100cm
0.8m = 100*0.8 = 80cm
(2•7)-5
14-5= 9
So the answer is 9
Since all the inside angles are 60, in order to add up to 180, the outside angles need to be 120.
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>
