Answer:
$5202
Step-by-step explanation:
The total surface area of the cuboidal hall is:
2LB + 2BH + 2LH.
This will be: 2(40*3) + 2(3*15) + 2(40*15)
which will give : 1530m square.
The cost of 25msq of paint is 10
then the cost of 1530 will be 1530x10/25 = 612.
The cost of 1msq of tiles is 3
then the cost of 1530 will be 1530 x 3
= 4590.
Then the total cost will be =$5202
$1,370
Explanation:
$35 •4=$140
$140•8=$1,120
$1,120+$250=$1,370
1/2 ÷ 1/2
= 1/2 ÷ 2/1
= 1/2 × 2/1
= 2/2
= 1
8-4(5)+12
8-20+12
20-20
0
Hope this helps :)
