Question

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

Answer 1

Answer:

72L

Step-by-step 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 × $\frac{2}{7}$ = 48

This means Tank B currently holds 48L of water

120 - 48 = 72L

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