An aquarium has a base in the shape of a trapezoid. The base is 100
Nat2105 [25]

Answer:

Volume = 210L

Step-by-step explanation:

Given

Base:

Front = 100cm

Back = 50cm

Width = 40cm

Height = 70cm

Required

Determine the volume (in litres)

First, we need to calculate the area;

Base on the parameters given, we have:

Area = \frac{1}{2}(Front + Back) * Width

Area = \frac{1}{2}(100cm + 50cm) * 40cm

Area = \frac{1}{2}(150cm) * 40cm

Area = 75cm * 40cm

Area = 3000cm^2

Volume = Area * Height

Volume = 3000cm^2 * 70cm

Volume = 210000cm^3

1cm^3 = 0.001L

So:

Volume = 210000 * 0.001L

Volume = 210L
