A cuboid has a square base of side x cm. The volume of the cuboid is V cm^3 and the height is h cm.
Lemur [1.5K]
You will need the formula for finding the volume of a rectangular prism (cuboid).
V = l x w x h

1. V = x^2 x h

2. To solve for x, you will substitute in the information you know.

150 = x^2 x 24
Divide both sides by 24 to get

6.25= x^2
The square root of 6.25 is 2.5.

x = 2.5 cm

How would you combine the area of the top circle, bottom circle, and rolled-out the cylinder to make the total surface area?
aliya0001 [1]

Answer:

The total surface area of a cylinder is equal to the sum of areas of all its faces. The total surface area with radius ‘r’, and height ‘h’ is equal to the sum of the curved area and circular areas of the cylinder.

TSA = 2π × r × h + 2πr2= 2πr (h + r) Square units

Answer:

66 cm

Step-by-step explanation:

Let's define the circumference first.

It is the boundary of any curved geometric figure specially circle.

We are given the diameter of the circle in the diagram

The diameter is:

d = 21 cm

to find the circumference, we have to find the radius of the circle first.

As radius is half of diameter

d = r/2

= 21/2

= 10.5 cm

The formula for circumference is:

C = 2\pi r\\Putting\ the\ values\\C = 2 * \frac{22}{7}*10.5\\ C = \frac{462}{7}\\ C= 66\ cm

The circumference is 66 cm ..
