Answer :
Volume of a pyramid = Base Area × height / 3 ;
Volume of a prism = Base Area × height ;
Then, Volume of a prism = 3 × Volume of a pyramid = 3 × 90 = 270 [tex] m^{3} [/tex];
Volume of a prism = Base Area × height ;
Then, Volume of a prism = 3 × Volume of a pyramid = 3 × 90 = 270 [tex] m^{3} [/tex];
