1.	If the base of right rectangular prism remains constant and the measures of the lateral edges are halved, then its volume will be reduced by :(a) 50% (b) 33.33% (c) 66.66% (d) None of these
Answer» (a) 50% Volume of a prism = Area of base × height. Since, the base area is constant and the height is halved, so the volume will also be halved, i.e. volume will be reduced by 50%.

Answer»

(a) 50%

Volume of a prism = Area of base × height.

Since, the base area is constant and the height is halved, so the volume will also be halved, i.e. volume will be reduced by 50%.
