The surface area of the composite shape is 1560 square inches
<u>Step-by-step explanation:</u>
The surface area of the top cardboard is,
SA = 5 x area of each side
Because one side is attached with another cardboard box . So while finding the area only 5 sides are calculated.
SA = 5 ( 10 x 10)
= 500 square inches
The surface area of the rectangular prism cardboard,
Given that,
l = 20 in
w =15 in
h = 8 in
A = 2(lw + wh + hl) - 100
We are subtracting 100 because it is the area of one side of the square cardboard box on top of the rectangular prism box .
A = 2(300 + 120 + 160) - 100
= 2(580) - 100
= 1160-100
= 1060 square inches
Total surface area = SA + A
= 500 + 1060
= 1560 square inches
Probability1 *Probability2
0.35 = 0.48 * P2
0.35/0.48 = P2
P2 = 0.7291666...,

Answer:
The surface area of the prism is equal to 72 sq inches.
Step-by-step explanation:
Given that,
A rectangular prism with a length of 7 inches, a width of 3 inches, and a height of 1 1/2 inches.
The surface area of a rectangular prism is given by :

Put all the values,

So, the surface area of the prism is equal to 72 sq inches.
The answer is A=58 i think
