Find the area of a square whose perimeter is 40cm
If the perimeter of a square is 40cm, then each side length is 10cm (since all sides of a square are equal).
To find the area of the square, we use the formula:
Area = Side length x Side length
Plugging in our value for the side length:
Area = 10cm x 10cm
Area = 100cm²
Therefore, the area of the square is 100cm².
How many numbers between 9 and 49 are divisible by 6?
The first multiple of 6 that is greater than or equal to 9 is 12. The last multiple of 6 that is less than or equal to 49 is 48. We need to count the number of multiples of 6 that are between 12 and 48 (inclusive).
To do this, we can list the multiples of 6 in this range and count them:
12, 18, 24, 30, 36, 42, 48
There are 7 numbers in this list, so there are 7 numbers between 9 and 49 that are divisible by 6.
If m=4 and n = 3 what is the value of the product of (m+n) and (m_n)?
Assuming that the underscore between m and n is meant to indicate multiplication, we can solve the problem as follows:
(m+n) = (4+3) = 7
(m_n) = (4_3) = (4 x 3) = 12
The product of (m+n) and (m_n) is obtained by multiplying these two values:
(m+n) x (m_n) = 7 x 12 = 84
Therefore, the value of the product of (m+n) and (m_n) is 84.
Formula of volume of a cube?
The formula for the volume (V) of a cube is:
V = s^3
where s is the length of one side of the cube.
In other words, to find the volume of a cube, you simply need to cube the length of one of its sides.
Find the volume of a cube with sides 4cm
Using the formula for the volume of a cube:
V = s^3
where s is the length of one side of the cube.
If the length of each side of the cube is 4cm, then we can substitute s = 4cm into the formula:
V = 4cm^3
Simplifying:
V = 64cm³
Therefore, the volume of the cube is 64 cubic centimeters (cm³).
