Answer:
a.) perimeter: 48 yards area: 96 sq. yds
b.) perimeter: 39 feet area: 74.36 ft. sq.
Step-by-step explanation:
a.) perimeter: 16 + 20 + 12 = 48 area: height * base / 2 = 96
b.) perimeter: (14.3 * 2) + (5.2 * 2) = 39 area: Length * Width = 74.36
Answer:
The whole number dimension that would allow the student to maximize the volume while keeping the surface area at most 160 square is 6 ft
Step-by-step explanation:
Here we are required find the size of the sides of a dunk tank (cube with open top) such that the surface area is ≤ 160 ft²
For maximum volume, the side length, s of the cube must all be equal ;
Therefore area of one side = s²
Number of sides in a cube with top open = 5 sides
Area of surface = 5 × s² = 180
Therefore s² = 180/5 = 36
s² = 36
s = √36 = 6 ft
Therefore, the whole number dimension that would allow the student to maximize the volume while keeping the surface area at most 160 square = 6 ft.
