The volume of the right rectangular prism is 3.75 cubic inches.
To find the volume of the right rectangular prism, we'll use the formula: Volume = length × width × height. The given dimensions are:
Length = 2 inches
Width = 1 (1/4) inches
Height = 1 (1/2) inches
Now, substitute these values into the formula:
Volume = 2 inches × 1 (1/4) inches × 1 (1/2) inches
To multiply these fractions, convert the mixed numbers to improper fractions:
Volume = 2 inches × (5/4) inches × (3/2) inches
Multiply the numerators and denominators:
Volume = (2 × 5 × 3) / (4 × 2) = 30 / 8 = 15 / 4 = 3.75 cubic inches.
None of the provided answer choices (A, B, C, D) matches the calculated volume of 3.75 cubic inches.
