To find: the additional information needed to find the cost of the soil
Answer to Problem 34STP
The the additional information needed is the height of the bricks
Explanation of Solution
Given:
Thedimension of the garden is
The cost of soil is $9 per cubic ft.
Calculation:
The objective is to identify the missing information from the given condition.
The figure will be a rectangular prism.
The volume V of the rectangular is given by the formula
Where B is the area of a face and h is the base height of the prism.
The area Bof the rectangle is given by
Put
Thus, the volume V is
To find the volume h is required. Since the cost of soil is $9 per cubic ft. so the total cost
s of the soil is
To find the total cost of the soil it is required to the value of that is the height of the brick.
Thus, the correct choice is (D).
Conclusion:
Therefore, the correct choice is
