You can solve for the Lateral Surface Area of a rectangle by using the following equation:
L.S.A = 2h(l + w)
In the case of the given rectangular prism,
l = 5
w = 2
h = 3
Plug in the corresponding numbers to the corresponding variables:
L.S.A = 2(3)(5 + 2)
Simplify. Remember to follow PEMDAS.

First, solve for the parenthesis:
L.S.A = 2(3)(7)
Multiply:
L.S.A = 6 * 7
L.S.A = 42
Your lateral surface area = 42

Solve for your surface area.
The surface area of a rectangular prism can be solved using the following equation:
S.A = 2lw + 2wh + 2lh
Let:
l = length = 5
w = width = 2
h = height = 3
Plug in the corresponding numbers to the corresponding variables;
S.A = 2(5)(2) + 2(2)(3) + 2(5)(3)
Simplify. Remember to follow PEMDAS. First multiply, then add:
S.A = (20) + (12) + (30)
S.A = 62
Your total surface area = 62

I think it may be this one 40×9=360
Answer:
14. 104 degree
15. 23.5 degree
16. -4 degree
Step-by-step explanation:
14. x+6 = 110
15. 46+4x+40 = 180
16. 62-2x+90-5x = 180
5 cents is the answer because u can use 7 5 cent pieces or a 25 cent peice and 10 cent piece to get 35. 7-2=5
