Selina is picking strawberries. She is using 5 boxes to hold them all. Each box has a width of 6 in, a height of 3 in, and a length of 4 in. What is the total volume of all 5 boxes? Explain how to solve this problem.
The volume of a cuboid is the product of its length, width, and height. The total volume with Selina is 360 in³.
What is the volume of a cuboid?The volume of a cuboid is the product of its length, width, and height. It is represented as,
[tex]\rm \text{Volume of Cuboid} = (Length \times Width \times Height)\ unit^3[/tex]
The volume of each of the boxes with a width of 6 in, a height of 3 in, and a length of 4 in, can be written as,
[tex]\rm \text{Volume of a single Box} = 6\ in \times 3\ in \times 4\ in = 72\ in^3[/tex]
Now, the total number of boxes Selina has is 5, therefore, the total volume with Selina can be written as,
[tex]\rm \text{Total\ Volume} = \text{Volume of a single box} \times 5 = 72\ in^3 \times 5 = 360\ in^3[/tex]
Hence, the total volume with Selina is 360 in³.

=1000(2^30-1)/2-1
The geometric series given as 1000, 500, 250, 125,... is seen to be; Convergent.
What is divergent or convergent series?
A series is said to be divergent if it doesn't converge at any finite point. However, a series is said to be convergent if it converges at a finite point.
In this question, we see the series progressively reducing by one quarter of the previous number. Thus, it means that the sequence will converge close to zero and as such we can say taht the sequence is convergent.
Formula for sum of geometric series is;
Sₙ = a(1 - rⁿ)/(1 - r)
Thus;
S₁₀ = 1000(1 - 0.5¹⁰)/(1 - 0.5)
S₁₀ = 1998.05
Sum of first 30 terms is;
S₃₀ = 1000(1 - 0.5³⁰)/(1 - 0.5)
S₃₀ = 2000

The sum of two numbers is 53 The larger number is 11 more than the smaller number. What are the numbers?
Answer:
21 and 32 are the numbers
Step-by-step explanation:
Let assume that the the two numbers are X and Y and that X is the large number.
According to the question,
X + Y = 53 .................. Equation 1
then, X = 11 + Y........... Equation 2
Substitute equation 2 into equation 1.
[11 + Y] + Y = 53
11 + 2Y = 53
2Y = 53 - 11 = 42
2Y = 42
Y = 42 / 2 = 21,
Therefore, Y = 21 [Small number].
According to equation 1,
X +Y = 53
X + 21 = 53
X = 53 - 21 = 32.
Therefore, X = 32 [Big number]

An inground swimming pool contains 2.3 times 10 superscript 4 units of water. which unit of measure was used? teaspoons cubic centimeters fluid ounces gallons
The measurement unit used for the water in the swimming pool is 2.3×10⁴ gallons.
What is the Unit conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimeter is equal to 10 mm,
Though the real measurement is still the same the units and numerical values have been changed.
As it is given, the pool's volume or the amount of water in the pool is equal to 2.3×10⁴ units.
We know that an average swimming pool has a volume of water that is in gallons, therefore, the unit of water that will be filled in the swimming pool will be equal to 2.3×10⁴ gallons.
Hence, the measurement unit used for the water in the swimming pool is 2.3×10⁴ gallons.
