Answer:
The volume of the stones is 382 cube inches.
Step-by-step explanation:
The dimensions of the aquarium are;
length = 16 inches
width = 8 inches
height = 10 inches
The height of the water in the aquarium = 4 inches
i. Volume of the water in the aquarium = length x width x height
= 16 x 8 x 4
= 512 cube inches
The volume of water in the aquarium is 512 cube inches.
ii. The new height of water = 7 inches.
New volume of water = 16 x 8 x 7
= 896 cube inches
The new volume of water is 869 cube inches.
The volume of the stones = New volume of water - initial volume of water
= 869 - 512
= 384 cube inches
The volume of the stones is 382 cube inches.
