Q.7 Shanti Sweets Stall was placing an order for making cardboard boxes for packing their sweets. Two sizes of boxes were required. The bigger of dimensions 25 cm × 20 cm × 5 cm and the smaller of dimensions 15 cm × 12 cm × 5 cm. For all the overlaps, 5% of the total surface area is required extra. If the cost of the cardboard is Rs 4 for 1000 cm2, find the cost of cardboard required for supplying 250 boxes of each kind.
Ans
Total surface area of bigger box
= 2(lb + bh + hl)
= 2(25×20+ 20×5+ 5×25)
= 2 (725)
= 1450 cm2
Required extra surface area = 5% of 1450 cm2
=72.5 cm2
Total surface area of smaller box
= 2(lb + bh + hl)
= 2(15×12+12×5+ 5×15)
= 2 (315)
= 630 cm2
Required extra surface area = 5% of 630 cm2
=31.5 cm2
Total required cardboard for both types boxes
= 1450 + 72.5 + 630 + 31.5
= 2184 cm2
Total required cardboard for both types 250 each boxes
= 250 x 2184 cm2
= 546000 cm2
Cost of 1000 cm2 cardboard = Rs. 4
Cost of required cardboard = Rs. (4/1000) x 546000
= Rs. 2184
Q.8 Parveen wanted to make a temporary shelter for her car, by making a box-like structure with tarpaulin that covers all the four sides and the top of the car (with the front face as a flap which can be rolled up). Assuming that the stitching margins are very small, and therefore negligible, how much tarpaulin would be required to make the shelter of height 2.5 m, with base dimensions 4 m × 3 m?
Ans
The length of shelter = 4 m
The breadth of shelter = 3 m
The height of shelter = 2.5 m
Total surface area of shelter of car
= lb + 2(b + l) × h
= 4 × 3 + 2(3+ 4)× 2.5 m2
= 12 + 35
= 47 m2
Thus, the required tarpaulin for shelter of car is 47 m2.
