Answer:
Option (3)
Step-by-step explanation:
Since density on an element = [tex]\frac{\text{Mass}}{\text{Volume}}[/tex]
Volume of the water in the aquarium = volume of the aquarium
= Length × width × height
= 10 × 5 × 5
= 250 cm³
We know density of the water = 1 gram per cm³
By putting these values in the formula,
1 = [tex]\frac{\text{Mass}}{250}[/tex]
Mass = 250 g
Therefore, Option (3) will be the answer.
