A.144
B.14.4
C.33.6
D.336



Text Answer


Capacity of tank = 120 x 80 x 50 = 480 000 cm³

Convert to liters =480,0001000=480𝑙𝑖𝑡𝑟𝑒𝑠

Volume of water poured into tank = 120 x 80 x 15 = 144,000 cm³

Convert volume into liters =144,0001000=144𝑙𝑖𝑡𝑟𝑒𝑠

Volume of water needed = 480 –144 = 366 liters

The correct answer is D (336).
