## Elementary Technical Mathematics

$V = l \times w \times h$ $V=5 ft \times 6 ft \times 5 ft = 150 ft^{3}$ Since the weight given is for one cubic foot, multiply by the volume to find the total weight. Multiply by the conversion factor to convert pounds to tons, $150 ft^3 \times 40\frac{lb}{ft^3} \times \frac{1 ton}{2000 lb} = 3 tons$
