Answer:
i think t is 1067.66
Step-by-step explanation:
volume of a square pyramid: V=a^2*h/3 since it is square all sides are equal
a=10, the height=18-7=11
V=10^2*11/3= 366.67 cm^3
the volume of the square pyramid= Area *height= length*width*height
V=10*10*7=700 cm^3
volume of the shape is : 366.67+700=1066.66
