The volume of the fish tank is 633,957.5 cubic cm or 0.634 cubic meter.
The formula for calculating the volume of a cuboid is
= length × breadth ×height
Given :
the length of fish tank = 105 cm
The width of fish tank= 75 cm
The height of fish tank= 80.5 cm
So, the volume of the fish tank =105×75 ×80.5
=633,957.5

In metric units ;
1 meter = 100 cm
So, converting all the dimensions into metric units.
length of fish tank = 1.05 m
width of fish tank = 0.75 m
height of fish tank = 0.805 m
So, the volume of fish tank = 1.05 x 0.75 x 0.805
= 0.6339575
or
= 0.634
