Question

an aquarium tank that measures 2.4 m high, 6 m long, and 1.5 m wide is completely filled with water. the density of water is 1,000 kg/m³. what is the mass of the water in the tank? a. 46 kg b. 101 kg c. 9,900 kg d. 21,600 kg

Explanation:

Step1: Calculate tank volume

Volume = length × width × height = $6 \times 1.5 \times 2.4$
$V = 6 \times 1.5 \times 2.4 = 21.6 \, \text{m}^3$

Step2: Calculate water mass

Mass = density × volume = $1000 \times 21.6$
$m = 1000 \times 21.6 = 21600 \, \text{kg}$

Answer:

D. 21,600 kg
