(a)
Find the area in square feet of the structure’s surfaces that lie above the ground.
(a)
Answer to Problem 28PPS
Explanation of Solution
Given:
The structure is hollow rectangular prism 9 feet tall, 4 feet wide , and 1 foot deep.
Formula Used:
The Lateral area L of a right prism is
L = Ph , where h is the height of the prism and P is the perimeter of a base.
The Surface area S of a right prism is
S = L + 2B , where L is its Lateral area and B is the area of a base.
Calculation:
The base of the prism is rectangle , whose length is 1 foot and width is 4 feet.
Perimeter of the base of the rectangle= P = 2(1+4) = 10 ft. [perimeter of rectangle = 2(length + width) ]
Lateral area = Ph =
The base of the prism is rectangle , whose length is 1 foot and width is 4 feet.
Area of the base of the prism = B =
Surface area of prism that is above the ground = L + 2B =
(b)
Find the area in square yards of the structure’s surfaces that lie above the ground.
(b)
Answer to Problem 28PPS
Explanation of Solution
