It is a square based pyramid where,
Length (l)=9
Height (h)=10
Slant height (s)=11

For, volume (V) = 1/3 l^2*h
=1/3 9^2*10
=1/3 *810
=270


For, surface area = 2sl
= 2*11*9
=198

Someone please explain how the GCF of x^4 and x^3 equals x^3. This has me stumped.
Ede4ka [16]

GCF is the greatest common factor. its the value of the factors that are common to both the numbers being compared. In other words the product of the factors that are common to both numbers or the greatest factor common to both numbers.
factors of x⁴ = x * x * x * x = (x * x * x) * x
factors of x³ = x * x * x = (x * x * x)
factors common to both are (x * x * x) Therefore GCF is x³
