Question

four hollow cubical boxes eac having outer edge 1m are joined to form a double bed in which top face is squre.if the wood used is of thickness 5cm and all the four boxes can be opened then what is the capacity of the boxes of the double bed in cubic meter

Answer 1

Answer:

Step-by-step explanation:

Outer edge of cube = 1 m

Thickness of wood used = 5 cm = 0.05 m

Hence inner edge of cubical box = 1 – 2(0.05)

= 1 – 0.1 = 0.9 m

Volume of cubical box = a3 cubic units

= (0.9)3 cu m

= 0.729 cu m

Hence volume of 4 cubical boxes = 4 x 0.729 = 2.916 cu m
