Question

Determine the total cardboard needed in cm cube to construct a box
If the width is 15.5 cm
Length is 190mm
Height is 0.15

Answer 1

Answer:

what is the unit of height ...u have not told that

Answer 2

Step-by-step explanation:

If h is assumed in cm

I. e. 0.15cm

convert all values into cm

length= 190mm

(1cm = 10cm )

length = 19cm

total surface area of cuboid is = 2 ( l×b + l×h + b×h)

= 2 ( 15.5 × 19 + 19×0.15 + 0.15 × 15.5)

= 2 (294.5 + 2.85 + 2.325)

=2 (299.35)

=599.35cm square
