Length of rodc layer=area divided by width= <br /> 750.0 ft� / 10.0 feet= 75.0 ft <br /> E. ROCK VOLUME <br /> 1. Mul6ply rock area by rock depth to get cubic feet of rock <br /> 750.0 X 1.0 ft= 750.0 ft3 <br /> 2. Divide ft tiy 27 ft/yd3 to get cubic yards <br /> 750.0 ft3 / 27 = 27.8 yd3 <br /> 3. Multiply cubic yards by 1.4 to get weight of rock in tons; <br /> 27.g yd3 X 1.4 toNyd3 = 38.9 tons <br /> Page 1 of 5 <br />
