What is a rectangular prism?
'In geometry, a rectangular prism is a polyhedron with two congruent and parallel bases. It is also called a cuboid.'
According to the given problem,
Volume of the cuboid = Length × Width × Height
= 30 × 20 × 15
= 9000 cubic centimeters
Now for the volume of the added water,
Length = 30 cm
Width = 20 cm
Height = 2.5 cm
V = 30 × 20 × 2.5
= 1500 cubic centimeters.
Hence, we can conclude, the volume of the added water is 1500 cubic centimeters.
