Calculating Solid Volume of Concrete per Sack of Cement
Explanation:
To determine the solid volume of concrete one could obtain per sack of cement, we need to calculate the volume of one sack of cement using the given ratios.
Given the ratios, the volume of cement = 1 x 94 = 94 cubic inches.
The solid volume of concrete per sack of cement = 94 cubic inches x (1 + 2.1 + 2.3) = 94 cubic inches x 5.4 = 508.8 cubic inches. Converting this to cubic feet, we get 508.8 / 1728 = 0.295 ft³. Therefore, the correct answer is 0.30 ft³.
