How many 4'x8' plywood is required to make a box my sizes are 160cm x110cm x 163cm?

Answer 1

The dimensions of the box are 160cm x 110cm x 163cm.

In order to build a closed box ... all six sides ... you need

-- two pieces 160cm x 110 cm = 2 x 17,600 cm2 = 35,200 cm2

-- two pieces 160cm x 163cm = 2 x 26,080 cm2 = 52,160 cm2

-- two pieces 110cm x 163cm = 2 x 17,930 cm2 = 35,860 cm2

-- Total material = 123,220 cm2

-- A 4ft x 8ft sheet = 48in x 96in = 4,608 x (6.4516 cm2 / in2 ) = 29,729 cm2 (rounded)

-- Your total material requirement is 123,220/29,729 = 4.145 sheets.

Note:

That result refers only to the total area required. I'm not getting into

how you would cut the pieces you need out of 4' x 8' sheets so as to

minimize the amount wasted.
