costs 10
Answers
Answer:
If the measurement of the gift boxes are 14 inches* 6 inches * 4 inches and that of the wrapping sheets are 32 inches* 4 inches, and if Poonam had 160 such gift boxes, she needs 410 wrapping covers and it costs Rs 4100 if the cost of one wrapping sheet is Rs 10
Step-by-step explanation:
Given
number of gifts Poonam has to wrap = 160
Measurement of each gift box = 14 inches* 6 inches * 4 inches
The surface area of the gift box ( cuboid) = 2(lb+bh+hl)
= 2( (14*6)+(6*4)+(4*14))
= 2(84+24+56)
= 2*164
= 328 square inches
Area of 160 such boxes = 328*160 =52480 square inches
Length of wrapping sheet = 32 inches
Width of the wrapping sheet = 4 inches
Area of the wrapping sheet ( rectangle) = l*b = 32*4 =128 square inches
Number of wrapping sheets required to cover 160 gift boxes = 52480/128
=410
So, 410 wrapping sheets are needed in total
Cost of 1 wrapping sheet = Rs 10
Do, cost of 410 wrapping sheets = 410*10 =Rs 4100
