Question

What is the total sum of the vertices, faces and edges of a closed cuboid

Answer 1

3(2g+3)+2(3g-2)

Answer 2

What is the sum of 13.96 and 3.0084 rounded off to the nearest hundredths

Answer 3

Yana cycled a distance of 25km 320m in 6 days. What distance did she cover in one day

Answer 4

A cuboid has 8 vertices, 6 faces, and 12 edges.

Therefore, the total sum of the vertices, faces, and edges of a closed cuboid is 8 + 6 + 12 = 26.

Answer 5

To simplify the expression 3(2g+3)+2(3g-2), we will follow the order of operations (also known as PEMDAS), which states that parentheses should be simplified first, followed by exponents, multiplication and division from left to right, and finally addition and subtraction from left to right.

3(2g+3) can be simplified as follows:
3(2g+3) = 6g + 9

2(3g-2) can be simplified as follows:
2(3g-2) = 6g - 4

Now, we can combine the simplified expressions:
6g + 9 + 6g - 4

Combining the like terms, we get:
12g + 5

Therefore, 3(2g+3)+2(3g-2) simplifies to 12g + 5.

Answer 6

The sum of 13.96 and 3.0084 is 16.9684.
Rounding off to the nearest hundredths, we get 16.97.

Answer 7

To find the distance Yana covered in one day, we divide the total distance she cycled by the number of days.

First, we need to convert the distance from kilometers and meters to meters.
25 km = 25,000 m (since 1 km = 1000 m)

Now, we can add the meters to get the total distance in meters:
25,000 m + 320 m = 25,320 m

Next, we divide the total distance by the number of days:
25,320 m / 6 days = 4219.33 m/day, which can be rounded to 4219.33 m/day.

Therefore, Yana covered a distance of approximately 4219.33 meters per day.
