Answer:

Question 1: C. 4 × 3 × 2 ×
(1)/(8) ×
(1)/(8) ×
(1)/(8)

Question 2: The volume is
(1)/(12) or 0.083333333

Question 3: The volume fo the solid figure is 234

Explanation:

1. Volume of a rectangular prism = (length × width × height) cubic units

Length = 4 ×
(1)/(8)

Width = 3 ×
(1)/(8)

Height = 2 ×
(1)/(8)

Volume = 4 ×
(1)/(8) × 3 ×
(1)/(8) × 2 ×
(1)/(8)

Volume = 4 × 3 × 2 ×
(1)/(8) ×
(1)/(8) ×
(1)/(8)

So the correct option is:

C. 4 × 3 × 2 ×
(1)/(8) ×
(1)/(8) ×
(1)/(8)

2.

We have to fold the shape into a rectangular prism, look at the picture

Volume of a right rectangular prism = (length × width × height)

Length =
(1)/(3)

Width =
(1)/(3)

Height =
(3)/(4)

Volume =
(1)/(3) ×
(1)/(3) ×
(3)/(4)

Multiply
(1)/(3) times
(1)/(3) by multiplying numerator times numerator and denominator times denominator.


( 1 * 1 )/( 3 * 3 ) * \left( ( 3 )/( 4 ) \right)

Do the multiplications in the fraction
( 1 * 1 )/( 3 * 3 )


( 1 )/( 9 ) * \left( ( 3 )/( 4 ) \right)

Multiply
(1)/(9) times
(3)/(4) by multiplying numerator times numerator and denominator times denominator.


( 1 * 3 )/( 9 * 4 )

Do the multiplications in the fraction
( 1 * 3 )/( 9 * 4 )


(3)/(36)

Reduce the fraction
(3)/(36) to the lowest terms by extracting and canceling out 3

Fraction form:
(1)/(12)

or

Decimal form: 0.083333333

So the volume of the right rectangular prism is
(1)/(12)

3. Look at the picture with the solid figure labeled

We can think of this shape as two different prisms ( A and B)

Volume of A = 4.5 × 6 × 6.5 = 175.5

Volume of B = 3 × 3 × 6.5 = 58.5

Total volume of the whole figure = 175.5 + 58.5

175.5 + 58.5 = 234

So the volume of the solid figure is 234
