A fish tank is in the shape of an open glass cuboid 30cm deep with a bade of 16cm by 17cm,these measurement being external. If the glass 0.5cm thick and its mass is 3g/cm^3,find
The mass of the tank in kg
Answered by oobleck
internal v = (30-0.5)(16-1)(17-1) = 7080 cm^3
mass = density * volume = 3*7080 = 21240g = 21.24 kg

internal Vol = (30-0.5)(16-1)(17-1) = 7080 cm^3 = 7.08ltrs
external Vol= 30* 16* 17 = 8160cm^3 = 8.16ltrs
Vol of thickness = 8160 - 7080 = 1080cm^3

Mass of the tank= density * volume = 3*1080 = 3,240g = 3.24 kg
