Answer to (a) = 3cm Answer to (b) = height is 12cm, area of base is 16 cm2
Formula for question a Height = (3)V/a^2 We know v=16, we know a is 4 Height = (3) 16/16 Height = (3)
Formula for question b If it’s similar, we will first find the ratio of V We know one pyramid V=16, the other is V=1024 16 to 1024 = 64 cm3, take cube root of that for a ratio of 4 Multiply your known measurements x 4 So height is 3 x 4 = 12 Base edge is 4 x 4 =16 Volume is known at 1024cm3
