Step-by-step explanation:
external dimensions= 27*19*11
width=1.5cm
thus the internal
length=27-1.5*2
=24cm
breadth=19-1.5*2
=16cm
height=11-1.5*2
=8cm
thus volume= lbh
=24*16*8
=3072cm^3
external volume=LBH
=27*19*11
=5643cm^3
i) volume of wood=ext vol- int vol
=5643-3072
=2571 cm^3
ii) cost = cost per cm^3*vol of wood
= 1.20*2571
=₹ 3085.20
iii) side of cube= 4cm
volume= a^3
= 4^3
=64 cm^3
no.of cubes= int.vol of box÷vol. of cube
=3072/64
=48
Step-by-step explanation:
Length of the open box = 27 cm
Breadth of the open box = 19 cm
Height of the open box = 11 cm
External volume of the open box = 27 * 19 * 11 = 5643 cm^3.
Thickness is 1.5 cm
Internal length of open box = 27 - (1.5 * 1.5) cm = 24 cm
Internal breadth of a open box = 19 - (1.5 x 1.5) cm = 16
Internal height of open box = 11 - 3 = 8 cm
Internal volume of open box = 24 * 16 * 8 = 3072 cm^3
(i)
Volume of wood in the box = 5643 - 3072
=> 2571 cm^3
(ii)
cost of wood = 2571 * 1.20 = 3085.2
(iii)
Number of cubes 4 cm.
= 24/4 * 16/4 * 8/4
= 6 * 4 * 2
= 48 cubes.
