Best ResponseYou've already chosen the best response.0h = height; l= slant length; say base = b; let area of base = A, perimeter of the figure be p

Best ResponseYou've already chosen the best response.0the the volume of the figure is given by Volume of pyramid = 1/3 * area of base *slant height Volume of pyramid =1/3 *A*l

Best ResponseYou've already chosen the best response.0okay so I'm trying to plug everything in but it says the pyramid is squared, it wouldn't really have five points like how you drew o: I'm a little confused on that

Best ResponseYou've already chosen the best response.0base can be any figure like rectangle or square or rhombus doesn't matter the area of the base changes according to the base figure

Best ResponseYou've already chosen the best response.0so for the second part we need to calculate the area of the base that is area of the square

Best ResponseYou've already chosen the best response.0so, (2916/3,136)*100 will give the required percentage = 92.98%

Best ResponseYou've already chosen the best response.0I forgot to divide the area of the pyramid by 3 that was in the formula

Best ResponseYou've already chosen the best response.0so, volume of pyramid A will be 972 cc not 2916, so, pyramid A/ Pyramid B = (972/3,136 )*100 = 31% so, final answer is => pyramid B hass 69% bigger volume than pyramid A @emilybbydoll
