Best ResponseYou've already chosen the best response.2Let's use volume formula of pyramid V = 1/3 * base area * height

Best ResponseYou've already chosen the best response.2V = 1/3 * base area * height V1 = 1/3 * (x)^2 * 6 V2 = 1/3 * (12)^2 * y

Best ResponseYou've already chosen the best response.2x is the side length of the base of the small pyramid y is the height of the larger pyramid

Best ResponseYou've already chosen the best response.0okay so how do i figure out the y then, im sorry i sound dumb im just confused. i know the formula but how do i do it wen i dont know the y

Best ResponseYou've already chosen the best response.2lol you're not dumb! :) Here see if you understand this :) Let's use volume formula of pyramid Volume = 1/3 * base area * height Given: V1 = 1/3 * (x)^2 * 6 V2 = 1/3 * (12)^2 * y We can find the scale factor A1 / A2 = (L1 / L2 ) ^2 = 9/16 L1 / L2 = √ 9/16 = 3/4

Best ResponseYou've already chosen the best response.0ok so the scale factor is 3/4. what's next

Best ResponseYou've already chosen the best response.2The scale factor is 3/4 to go from the bigger pyramid to the smaller pyramid

Best ResponseYou've already chosen the best response.2We can find the scale factor A1 / A2 = (L1 / L2 ) ^2 = 9/16 L1 / L2 = √ 9/16 = 3/4 The scale factor is 3/4 to go from the bigger pyramid length dimension to the smaller pyramid length dimension. The scale factor is 4/3 to go from the smaller pyramid length dimension to the bigger pyramid length dimension. V1 = 1/3 * (3/4 * 12) ^2 * 6 V2 = 1/3 * (12)^2 * (6 * 4/3)

Best ResponseYou've already chosen the best response.2Not quite... V1 = 1/3 * (3/4 * 12) ^2 * 6= 162
