9.) 6.5 ft

10.) 36 ft²

11.) 770 cm²

12.) 10,087 cm³

Step-by-step explanation:

9.) Find the height:

V = lwh

234 = 8(4.5)h

234 = 36h

/36     /36

6.5 = h

10.) Area of base:

B = lw

B = 8(4.5)

B = 36

11.) Area of the base:

B = lw

B = 35(22)

B = 770

12.) Volume of the pyramid:

V = Bh/3

V = 770(39.3)/3

V = 30,261/3

V = 10,087

12m

step-by-step explanation:
