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
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
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
