Question

A water tank is 9.5m long, 8m wide and 5m deep. (1000L= 1 m3

)


(a) What is the volume of the water tank?

(b) Calculate the capacity in liters of the tank.

(c) If gasoline costs $155 per liter, what is the cost of filling the tank?

Answer 1

Given

Length of the tank=9.5 m

The breadth of the tank=8  m

Height of the tank=5 m

1000L=1 m³

To Find

Volume, capacity in liters, the total cost of gasoline.

Solution

Length of the tank=9.5 m

The breadth of the tank=8  m

Height of the tank=5 m

The volume= length ×breadth×height

                   = 9.5×8×5

                   = 380 m³

The volume of the tank is 380 m³.

Given,

1000L= 1m³

Therefore,

380m³= 380×1000L

          = 380000L

The capacity in liters is 380000L

The cost of gasoline= $155 per litre

Therefore the cost of 380000L of Gasoline= 380000×155

                                                                        =$58900000

The cost of gasoline is $58900000.
