Question

Manav is painting a rectangular room and the dimensions of this room are
given by X.Y and Z feet. Manav takes 8 hours to paint a wall with
dimensions X and Z. He takes 4 hours to paint a wall with dimensions Y
and Z and 12 hours to paint the ceiling which has dimensions X and Y.
Manav works at a constant rate. X=6, what is the volume of the room.​

Answer 1

Answer:

mark as brain list pls I need 1 brainlist to complete

Step-by-step explanation:

48.75 is the volume of the room if you have thinking it is wrong no I learn this at 5 this question came I solve it

Answer 2

Answer:

36 cubic feet

Step-by-step explanation:

Here rate of work is area/hour which is constant for Manav

For XY dimension, the rate of work is X*Y/12=Y/2 as X=6 ----equation (1)

For XZ dimension, the rate of work is X*Z/8=6Z/8 as X=6 ----equation (2)

For YZ dimension, the rate of work is Y*Z/4 ----equation (3)

equating (1) and (3), as the rates of work are constant for each dimension

Y/2=Y*Z/4

Z=2

equating (1) and (2),

Y/2=6Z/8

Y=12/4=3

x=6, Y=3, Z=2

therefore volume=6*3*2=36 cubic feet
