We have that

1. Find the surface area of a square pyramid with a base length of 24 cm and a height of 16 cm

[surface area]=[area of 4 triangles sides]+[area of square base]
[area of square base]=24*24> 576 cm²

[area of one triangles side]
l=slant height
l²=16²+12²> l²=400> l=20 cm
[area of one triangles side]=24*20/2> 240 cm²
[area of 4 triangles sides]=4*240> 960 cm²
[surface area]=[960]+[576]> 1536 cm²

the answer part 1) is option B) 1536 cm²

2. Use 3.14 for π and round to the nearest tenth.
Find the surface area of the cylinder
radius=8 in
height= 8 in
[surface area]=2*[area of circular base]+[Perimeter of base]*h
[area of circular base]=pi*8²> 200.96 in²
Perimeter=2*pi*8> 50.24 in
[surface area]=2*[200.96]+[50.24]*8> 803.84 in²

the answer Part 2) is the option C) 803.8 in²

3. Find the volume of the cylinder.
[volume of the cylinder]=[area of circular base]*h
[volume of the cylinder]=[200.96]*8> 1607.68 in³

the answer Part 3) is the option A.) 1607.7 in.3

4.Find the volume of a rectangular prism with the following dimensions:
Length = 5 mm
Base = 7 mm
Height = 3 mm

[volume of a rectangular prism]=L*B*H

[volume of a rectangular prism]=5*7*3> 105 mm³

the answer part 4) is the option B.) 105 mm3

5.Find the volume of the given pyramid.
A large pyramid has a height of 7 yards, radius of 9 yards, and base of 7 yards.
this question is incorrect

the correct question is
5a) A large pyramid has a height of 7 yards and radius of 9 yards. (pyramid with circular base)
or 
5b) A large pyramid has a height of 7 yards and base of 7 yards. (pyramid with square base)

we will solve the two cases

5a) A large pyramid has a height of 7 yards and radius of 9 yards. (pyramid with circular base)
[volume of the pyramid]=pi*r²*h/3> pi*9²*7/3> 593.46 yd³

the answer Part 5a) is 593.46 yd³

5b) A large pyramid has a height of 7 yards and base of 7 yards. (pyramid with square base)

[volume of the pyramid]=b²*h/3> 7²*7/3> 114.33 yd³

the answer Part 5b) is 114.33 yd³

6.Find the volume of a square pyramid with a base length of 9 cm and a height of 4 cm.

[volume of a square pyramid]=b²*h/3> 9²*4/3> 108 cm³

the answer Part 6) is the option B.)108 cm³

I'm not sure exactly but my best guess would be 1/4
