Answer:
The capacity of the container does not depend on the outer dimensions. It depends on the internal dimensions. To find the internal dimensions of the box we have to subtract the thickness from the external dimensions. Therefore, the capacity of the box is 198702 cm³.
Step-by-step explanation:
For external box,
L=56 CM
B=39 CM
H=30 CM
VOLUME =L×B×H=56×39×30=65520 CM³
For internal ,
L=56−6=50 cm
B=39−6=33 cm
H=30−6=24 cm
VOLUME =L×B×H=50×33×24=39600 CM³
WOOD USED =65520−39600=25920 CM³
