A construction company builds a 15m by 10m rectangular house with a back deck of varying width x metres, as shown. Customers choose the width, x, of their deck. Calculate the total floor area for a customer who wants a deck 2 m wide.
Answers
Step-by-step explanation:
Surface Area (Circle): Radius x Radius x 3.14 (Radius = Diameter / 2)
Surface Area (Rectangle/Square): Length x Width
Volume (Circle/Rectangle/Square): Surface Area x Average Depth x 7.5
Average Depth: (Shallow Depth + Deep Depth) ÷ 2
FORMULA::-
Surface Area (Circle): Radius x Radius x 3.14 (Radius = Diameter / 2)
Surface Area (Rectangle/Square): Length x Width
Volume (Circle/Rectangle/Square): Surface Area x Average Depth x 7.5
Average Depth: (Shallow Depth + Deep Depth) ÷ 2
EXAMPLER::-
rectangular pool is 50 feet long by 20 feet wide. The shallow end is 3 feet deep and the deep end is 7 feet deep. Find the surface area and the volume.
Surface Area = Length x Width
Surface Area = 50 feet x 20 feet
Surface Area = 1,000 square feet
Volume = Surface Area x Average Depth x 7.5
Volume = 1,000 x Average Depth x 7.5
Average Depth = (Shallow Depth + Deep Depth) ÷ 2
Average Depth = (3 + 7) ÷ 2
Average Depth = 10 ÷ 2
Average Depth = 5
Volume = 1,000 x 5 x 7.5
Volume = 37,500 Gallons
ANSWER::-
1. Surface Area = 1,800 square feet Volume = 81,000 Gallons
2. Surface Area = 78.5 square feet Volume = 2,355 Gallons
3. Total Volume = 103,125 Gallons
