Why do you use cubic units and not square units to find the volume of solid figures?

Let's say you have a (1 unit) by (1 unit) by (1 unit) cube.

The Volume of this cube would be (considering a unit=u):

V=(1u)*(1u)*(1u)

=1*1*1*u*u*u

=1u³

The volume of this cube would be 1 unit^3 or in other words, 1 unit cubed.

--------------------------------------------------------

These solid figures are 3 dimensional entities. 3D shapes are made up of 3 elements: length, width and depth. Length, widths and depths are each 1 dimensional entities. Lengths emerge as points are dragged across a certain distance. Areas emerge as lengths are dragged across a certain distance. Volumes emerge as areas are dragged across a certain distance.

Area, A = Width, W* Height, H

Therefore,
W = A/H

Options:
At H = 4 ft, W = 60/4 = 15 ft
At H = 5 ft, W = 60/5 = 12 ft
At H = 6 ft, W = 60/6 = 10 ft

what is the value of the expression? 4(6/10−1/5)+0.4 enter your answer, in simplest form, in the box.
MA_775_DIABLO [31]

Answer: 2.0

Step-by-step explanation:

The given expression : 4(\dfrac{6}{10}-\dfrac{1}{5})+0.4

To solve the given expression , we need to follow BODMAS (Bracket→ Of Divide→ Multiplication →Add →Subtract).

According to BODMAS , first we simplified the expression present inside the brackets .

4(\dfrac{6-2(1)}{10})+0.4  [10= LCM[10,5]]

=4(\dfrac{6-2}{10})+0.4

=4(\dfrac{4}{10})+0.4

=(\dfrac{4\times4}{10})+0.4   [Multiply]

=(\dfrac{16}{10})+0.4   [Simplify]

=1.6+0.4=2.0 [Add]

Hence, the value of the expression in the simplified form = 2.0

3. Find the area of a semicircle with a diameter of<br> 30 inches.
slega [8]

Answer:

Answer:

Area of a CIRCLE with radius of 3 inches is

PI * radius^2 =

3.14159265 * 3^2 =

28.27433385  square inches.  

Since we are dealing with a SEMI-CIRCLE, we divide that by 2 and get:

14.137166925  square inches which rounds to about

14.14 square inches
