Step-by-step explanation:
Area of a trapezoid = (a+b)*h/2 so (100+150)*80/2
= 10000
Area of a rectangle = l*w so 48*64
=3072
10000-3072 = 6928
The surface area of a square pyramid is A=a^2+2a√a^2/4+h^2 which is A=4^2+2(4)√(4)^2/4+(5)^2 which = 59.08
Volume of a rectangular prism is l*w*h so 3.5*1.25*6 = 26.25 which is equal to 26 1/4
