Given:-
l = 15cm
b = 12 cm
h = 10 cm
it is also given that thickness is = 1cm
so,
internal length = 15 - 2 = 13cm
internal breadth = 12 - 2 = 10cm
internal height = 10 - 2 = 8cm
∴ volume of the rectangular box = volume of liquid that can be stored
→ volume of the rectangular box = l x b x h
= 13 x 10x 8
= 1040 cm³
∴ 1040cm³ of liquid can be stored in the rectangular box
l = 15cm
b = 12 cm
h = 10 cm
it is also given that thickness is = 1cm
so,
internal length = 15 - 2 = 13cm
internal breadth = 12 - 2 = 10cm
internal height = 10 - 2 = 8cm
∴ volume of the rectangular box = volume of liquid that can be stored
→ volume of the rectangular box = l x b x h
= 13 x 10x 8
= 1040 cm³
∴ 1040cm³ of liquid can be stored in the rectangular box

why we are doing -2 in dimension
to find the internal dimension
why -2 we can do -1 because thickness is 1cm

Given external length ,breath and height of box is 15cm ,12cm and 10 cm.
Therefore it's internal length breath and height of box will be 13 cm,10 cm and and 8 cm
Therefore column of the box = l × b× h
= 13 × 10 × 8
= 1040 cm ^3
Therefore it's internal length breath and height of box will be 13 cm,10 cm and and 8 cm
Therefore column of the box = l × b× h
= 13 × 10 × 8
= 1040 cm ^3
