(A) For the rectangular pack:Length $(l) = 5 \, cm$,Breadth $(b) = 4 \, cm$,Height $(h) = 15 \, cm$.Volume $= l 	imes b 	imes h = 5 	imes 4 	imes 15 = 300 \, cm^3$.Capacity of the rectangular pack $= 300 \, cm^3$.For the cylindrical pack:Base diameter $= 7 \, cm$,so Radius $(r) = \frac{7}{2} = 3.5 \, cm$.Height $(h) = 10 \, cm$.Volume $= \pi r^2 h = \frac{22}{7} 	imes (3.5)^2 	imes 10 = \frac{22}{7} 	imes 12.25 	imes 10 = 385 \, cm^3$.Capacity of the cylindrical pack $= 385 \, cm^3$.Comparing the two:$385 \, cm^3 - 300 \, cm^3 = 85 \, cm^3$.Thus,the cylindrical pack has a greater capacity by $85 \, cm^3$.
