The dimensions of water tank are 13cm, 10cm and 70cm. If it is half-filled with water, calculate the volume of water in litres
- A. 4.55 litres
- B. 7.50 litres
- C. 8.10 litres
- D. 9.55 litres
Correct Answer: A. 4.55 litres
Explanation
Vol of a cubiod = L x b x h
v = 13cm x 10cm x 70cm
= 9100cm
Since it is half-filled = \(\frac{9100}{2}\)cm
= 4550cm
4550cm \(\to\) 4.55 litres
