Question

75 boxes need to be gift wrapped. Find the length of the gifting paper of width 50cm needed to wrap
the gift boxes of dimensions 10 cm×5 cm×5 cm.​ please solve quickly ​

Answer 1

Given,

Total number of boxes = 75

Width of the gifting paper = 50 cm

dimensions of the gift box = 10cm ×5cm × 5cm

To find,

The Length of the gifting paper.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Surface area of a box = 2 × {(10×5)+(5×5)+(5×10)} = 2 × (50+25+50) = 2×125 = 250 cm²

Surface area of 75 boxes = 250×75 = 18750 cm²

Length of the gifting paper = 18750/50 = 375 cm

Hence, we need a Length of 375 cm for the gifting paper.
