what are those dimensions to? base side, slant height?
bace is 3ft side is 3ft and height is 6ft
height, or slant height? big difference.
i think slant im not sure
its slant
if slant height
area=3x3+4*1/2*6*3= 9+36=45ft^2
area=3x3+4*1/2*6*3= 9+36=45ft^2
so its 45FT^2?
oml thanks bobpursley thanks so much
