The volume of a room is 400 cu. m and its height is 25 m. find the cost of carpeting the floor of the room at 5 paisa per sq. cm.

Step-by-step explanation:

This only works if the room is a prism shaped, or cylinder.  

Volume of a prism or cylinder is area of he base times height.  So since we know the height and volume we can fand the area.

V = h*B

B = V/h

B = 400/25

B = 8

This is a very narrow room, anyway, the area of the base, which we want to carpet is 8 square meters. Can you figure out how much it will cost since each square meter will cost 5?

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
