Answer:

V=94.5 cm^3

Explanation:

Volume of a Prism: (B)H

B=Base Formula

H=Height of Prism

H=12

Triangle Base Formula: 1/2bh

b=3.5

h=4.5

Substitute Variables in formula:

V=[1/2(3.5)(4.5)](12)

Solve:

V=(7.875)(12)

V=94.5 cm^3

Answer:

Pretty sure it's 140.87 cm

Step-by-step explanation:

Multiply 3 1/2 by 4 1/4

Divide by two which is 7.43

Multiply 3 1/2 by 12

Now add 42+42+42+7.43+7.43

OR

126+14.87
