Answer:
4.1 billion
Step-by-step explanation:
1 ft = 30.48 cm
1 in = 2.54 cm
The volume of rain that fell on the roof is given by ...
V = LWH
V = (175 ft × 30.48 cm/ft)(45 ft × 30.48 cm/ft)(11 in × 2.54 cm/in)
= 175×45×11×30.48²×2.54 cm³ = 204,412,236.336 cm³
At 20 drops per cm³, this will be ...
20×204,412,236.336 ≈ 4,088,244,727 . . . . raindrops
About 4.1 billion raindrops fell on your roof.
A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
3² = 3 X 3 = 9
4³ = 4 x 4 x 4 = 64
= 2 x 2 x 2 x 2 x 2 x 2 = 64
The exact value in fractions are:
a) 1/9
b) 1/64
c) 1/64
<h3>What is a fraction?</h3>
A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
Example: 1/2, 1/3 is a fraction.
We have,

= 1/3²
3² = 3 X 3 = 9
= 1/9

= 1/4³
4³ = 4 x 4 x 4 = 64
= 1/64

= 1/
= 2 x 2 x 2 x 2 x 2 x 2 = 64
= 1/64
Thus.,
The exact value in fractions are:
a) 1/9
b) 1/64
c) 1/64
