Given = rectangular prism of measure 7.5 cm by 12 cm by 15.5 cm.
i.e length = 7.5 cm
breadth = 12 cm
height = 15.5 cm
Find out volume of the rectangular prism.
To proof -
Formula
Volume of the rectangular prism = length× breadth× height
= 7.5× 12× 15.5 cm³
= 1395 cm³
The volume ofthe rectangular prism become 1395 cm³.
Hence proved
89 is prime 16 is composite 17 is prime 25 is composite
15) 5/8
16)21.16 meters
17)C
