Question

Of Tank A, which measures 80 cm by 30 cm by 50 cm, is filled with water

and of Tank is nilled with water. The ratio of the volume of water in
Tank A to that in Tank Bis 5. 2. How much more water is needed to up
Tarik ?​

Answer 1

72L

Explanation:

I'm assuming Tank A and Tank B have the same volume. The question has many typos and is a bit hard to understand

Tank A Volume

V = l × w × h

= 80 × 30 × 50

= 120,000cm²

Tank A Capacity = 120,000ml

=120L

The Question states that Tank A is filled to capacity which means Tank A currently holds 120L of water

Tank A:Tank B = 5:2 = 120:x

120 ÷ 5 = 24L

24 × 7 = 168

168 ×
`(2)/(7)` = 48

This means Tank B currently holds 48L of water

120 - 48 = 72L

∴72 more litres of water is needed to fill Tank B
