Find the volume of a rectangular block of ice 2 ft by 3 1/2ft 1//2ft.
To find the volume of a rectangular block, you multiply the length, width, and height.
Length = 2 ft
Width = 3 1/2 ft = 7/2 ft
Height = 1/2 ft
Volume = Length × Width × Height
= 2 ft × (7/2) ft × 1/2 ft
= 2 ft × (7/2) ft × 1/2 ft
To multiply fractions, you multiply the numerators together for the numerator and the denominators together for the denominator. Therefore,
Volume = (2 × 7 × 1) / (2 × 2 × 2) ft^3
= 14 / 8 ft^3
= 7/4 ft^3
Therefore, the volume of the rectangular block of ice is 7/4 cubic feet or 1 3/4 cubic feet.
