Frame shown thick An aquarium with a square base has no top. There is a metal frame. Glass costs 7 dollars \( / \mathrm{m}^{2} \) and the frame costs 2 dollars \( / \mathrm{m} \). The volume is to be \( 20 \mathrm{~m}^{3} \). Express the total cost \( C \) in terms of the height \( h \) in meters. Hint: Work out the cost of the glass and frame separately. \[ C(h)=\$ \]
