Question

An aquarium has a base in the shape of a trapezoid. The base is 100

Answer 1

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:

$Volume = 210000 * 0.001L$

$Volume = 210L$
