Sorry but..I don't even know where to start. Good luck!
The volume of a figure is the number of cubic units present in the figure. For this problem, we assume that the figure would be a rectangular box in shape. So, the volume would be calculated by the product of its length, width and height or in this case the depth. We calculate the volume of water as follows:
Volume = 4.50 ft x 7.00 ft x 5.00 in ( 1 ft / 12 in )
Volume = 13.125 ft^3
We need to convert the resulting volume in liters. We do as follows:
Volume = 13.125 ft^3 ( 0.3048 m / 1 ft )^3 ( 1000 L / 1 m^3 )
Volume = 371.66 L
Are there any answer choice?
