Calculate the work in megajoules \( \left(1 \mathrm{MJ}=1 \times 10^{6} \mathrm{~J}\right) \) required to pump all the water out of a full trough from which water exits by pouring over the sides. Assume that \( a=11 \mathrm{~m}, b=18 \mathrm{~m}, c=10 \mathrm{~m} \), and \( h=4 \mathrm{~m} \). The density of water is \( 1000 \mathrm{~kg} / \mathrm{m}^{3} \), and \( \mathrm{g}=9.8 \mathrm{~m} / \mathrm{s}^{2} \). (Use decimal notation. Give your answer to two decimal places.) work \( \mathrm{MU} \)
