What is 8x43 in expanded form

8×43=8×(40+3)

⇒8×43=(8×40)+(8×3)

⇒8×43=(320)+(24)

⇒8×43=344=300+40+4

Step-by-step explanation:

Given product:- 8×43

First expand 43 = 40+3 in the product, we get

8×43=8×(40+3)

⇒8×43=(8×40)+(8×3) [Distributive property]

⇒8×43=(320)+(24)

⇒8×43=344

Now, We can write 344 in expanded form as

344=300+40+4

In words 344=3 hundreds+4 tens+4ones.

Therefore, 8×43=300+40+4

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
