Question 4

Nets & Surface Area rectangular prism

Answer 4

A net is the resulting shape of a 3-dimensional figure being laid flat. It is useful in helping us to determine which shapes make up a 3-dimensional figure as well as surface area

Question 5

volume of rectangular prism
the base is 5in by 7in
the height is 21in

Answer 5

V=B(h)
V=B(21in)
B=b(h)
B=5in(7in)
B=35in^2
V=35in^2(21in)
V=735in^3

Question 6

the diameter of the circle is 2.34 in

Answer 6

Circumference=2.34(𝝅) 
C=7.3476in
pi=C/D
P=7.3476/2.34
P=3.14
