1152 ft^2
Step-by-step explanation:
There are 7 faces on this solid.
I will label the faces and will calculate each area with an explanation.
Faces 1 and 2:
The front face and the back face are congruent and have 5 sides each. Each face is a rectangle with a triangle above it. The lower rectangular part has dimensions 9 ft by 12 ft. The triangle above the rectangle has base 9 ft and height 16 ft - 12 ft = 4 ft.
Each face is a rectangle and a triangle.
area = area of rectangle + area of triangle
area = LW + bh/2
area = 9 ft * 12 ft + 9 ft * 4 ft/2 = 108 ft^2 + 18 ft^2 = 126 ft^2
This is area of of face 1, the front face. Face 2, the rear face has the same area.
A1 = 126 ft^2
A2 = 126 ft^2
Face 3: The bottom of the solid is a rectangle measuring 9 ft by 20 ft
area = LW
area = 9 ft * 20 ft = 180 ft^2
A3 = 180 ft^2
Faces 4 and 5:
The left vertical face and the right vertical face are congruent rectangles measuring 12 ft by 20 ft.
area = LW
area = 12 ft * 20 ft = 240 ft^2
A4 = 240 ft^2
A5 = 240 ft^2
Faces 6 and 7 are the top right and left inclined rectangles. They are congruent, and each one has dimensions 6 ft by 20 ft.
area = LW
area = 6 ft * 20 ft = 120 ft^2
We need 2 of these area.
A6 = 120 ft^2
A7 = 120 ft^2
total surface area = A1 + A2 + A3 + A4 + A5 + A6 + A7
total surface area = 126 ft^2 + 126 ft^2 + 180 ft^2 + 240 ft^2 + 240 ft^2 + 120 ft^2 + 120 ft^2
total surface area = 1152 ft^2

Questionwhat is 10*10
AnswerStep-by-step explanation:
We could look at our fingers and count to 10 and do this 10 times each to get your answer 100. Or we could do 10 x 9 which gave us the Answer 90 and then you could just add 10moreto get the Answer 100
hence, The Answer is 100 :)
