Question

Ajay has built a cubical water tank in his house . The top of the water tank is covered with lid . He wants to cover the inner surface of the tank including the lid with square tiles of sides 25 cm . If each inner edge of the water tank is 2 m long and tiles cost rupees 360 per dozen then find the total amount required for tiles .


plzzzzzz answer the question

Answer 1

Side of cube= 2m
Area of the cube = 2*2*6= 24 sq. m
Area of tiles= 0.25*0.25= 0.0625 sq m

Number of tiles= 24/ 0.0625 = 384
no of tiles per dozen=384÷12=32
tiles cost per dozen=rs360
tiles cost 360 dozen=rs(32×360)=rs11520
I hope it is right and helps you .
