Question

a box without a lid is made of wood which is 3 cm thick its external dimensions are 86 cm × 60 cm × 45 cm. find the capacity of box in cube cm.

Answer 1

Answer:

first we have to find the volumn

Step-by-step explanation:

86×60×45= 232200

then

86-3=83

60-3=57

45-3=42

83×57×42=198702

232200-198702=33498

Answer 2

Given: Thickness of the box = 3cm

External length = 86 cm

External breadth = 60 cm

External height = 45 cm

To Find:Capacity of the box

Solution:

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.

Internal length = External length - thickness

                         = 86 - 3

                         = 83 cm

Internal breadth = External breadth - thickness

                            = 60 - 3

                            = 57 cm

Internal height = External height - thicnkess

                         = 45 - 3

                         = 42 cm

Volume of the box = Length x Breadth x Height

                               = 83 x 57 x 42

                               =  198702  cm³

Therefore, the capacity of the box is 198702  cm³.
