Answer:
Step-by-step explanation:
Let's find the volume of the room in ft³ and that will give
14×22×9=2772ft³
There are deductions. Hence we subtract them from this value
3×5=15, but there are two, hence 15×2=30ft²
And 4×7=28ft²
Hence 2772-(30+28)=2714
Dividing this value by 320 gives
8.4(to 2s.f)
Use the tens.Try 30x80. 76 rounds up to 80 and 33 rounds down to 30.
