Question

a room is 5.5m long4.5wide and 3.5 high find the most of white whasing ots wall at 120 per squre meter​

Answer 1

Answer:

hey my dear user here's your answer

RS :- 9653.75

Step-by-step explanation:

A room has length , breadth , height

here we have to multiply the numbers like this

Length × Breadth × Height

5.5. × 4.5. × 3.5

now here we have to take out the decimals

the answer is like this

55 × 45 × 35

= 86,625

then there are only tenths so the answer is like this

= 86.625

now per sq. m. = RS 120

here 86 is only there and others are after point so it can not include

now 86 × 120 = RS 9600

and now multiply the numbers after the point

= 0.625 × 86

= RS. 53 . 75

now add the numbers

9600 + 53 . 75

= 9653.75

Therefore, we need 9653.75 RS to white wash the room
