Answer» The cost of larger box is Rs 197.6 and smaller box is Rs 63.232 Step-by-step explanation: i) Bigger box: L = 20 cm = 0.2 m W = 15 cm = 0.15 m H = 5 cm = 0.05 m hence total surface area = 2(LW + LH + WH) = 2(0.2x0.15 + 0.2x0.05 + 0.15x0.05) = 2(0.03 + 0.01 + 0.0075) = 0.095 m² 4% of TSA is used for overlapping = 0.04 x 0.095 = 0.0038 Hence Net card board used for 1 larger box = 0.095 + 0.0038 = 0.0988 Net card board used for 200 larger box = 200 x 0.0988 = 19.76 m² Hence total cost of 200 box Rs 10 per m² = 10 x 19.76 = 197.6 ii) Smaller box L = 16 cm = 0.16 m W = 12 cm = 0.12 m H = 4 cm = 0.04 m hence total surface area = 2(LW + LH + WH) = 2(0.16x0.12 + 0.16x0.04 + 0.12x0.04) = 2(0.0192 + 0.0064 + 0.0048) = 0.0304 m² 4% of TSA is used for overlapping = 0.04 x 0.0304 = 0.001216 Hence Net card board used for 1 smaller box = 0.0304 + 0.001216 = 0.031616 Net card board used for 200 smaller box = 200 x 0.031616 = 6.3232 m² Hence total cost of 200 box Rs 10 per m² = 10 x 6.3232 = 63.232 Hence the cost of larger box is Rs 197.6 and smaller box is Rs 63.232 |
