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 × [tex]\frac{2}{7}[/tex] = 48
This means Tank B currently holds 48L of water
120 - 48 = 72L
∴72 more litres of water is needed to fill Tank B
