Outer dimensions = 60 x 45 x 32
Outer vol. = 86,400cm3
Inner dimensions =
(60cm - 5cm)x(45cm - 5cm)x(32cm - 5cm)
Inner volume =55cm x 40cm x 27cm
=54,000cm3
Volume of wood = outer vol. - inner vol.
86,400 - 54,000
=32,400cm3
Outer vol. = 86,400cm3
Inner dimensions =
(60cm - 5cm)x(45cm - 5cm)x(32cm - 5cm)
Inner volume =55cm x 40cm x 27cm
=54,000cm3
Volume of wood = outer vol. - inner vol.
86,400 - 54,000
=32,400cm3
