A) To calculate the surface area of the metal sheets used to make the water tank, we need to find the surface area of each side. Since it's a square based tank, there are 5 sides in total (4 sides + the bottom).
Each side will have the same area, as they are identical squares. The area of one side can be calculated as:
Area of one side = length x height
Area of one side = 4.5m x 3m = 13.5 square meters
Therefore, the total surface area of all sides used for the water tank is:
Total surface area = 5 x 13.5 square meters = 67.5 square meters
B) The cost of the metal sheets is $1,200 per square meter. Therefore, the total cost of the metal sheets used for the water tank is:
Total cost = 67.5 square meters x $1,200/square meter = $81,000
Therefore, Priscilla spent $81,000 on the metal sheets for the water tank.
Priscilla made a Square based water tank with an open top using metal sheets the tank was 4.5 m long and 3 m high
A) how many square meters of metal sheets were used
B) the cost of metal sheets is 1,200 per square meter how much did Priscilla spend on the metal sheets
