Answer:
390cm³
Step-by-step explanation:
IF you look at the figure attached, you will see that your figure is made up of 3 rectangular prisms.
All you need to do is solve for the volume of each prism and add them up together.
The formula to use to get the volume of a rectangular prism is:
Where:
V = Volume
w = width
l = length
h = height
Let's get the first one and double it because you have rectangular prisms with the same dimensions:
Next we get the rectangular prism in the middle:
Notice that the height of the side rectangular prisms is 12 cm. To get the height of the middle figure, just subtract 5cm and 2 cm from the height because they are the excess of the middle.
12cm - (5cm + 2cm)
12 cm - 7cm = 5cm
Then we plug it into the formula
Now that we have the volumes of all figures, just add them up together:
150cm³ + 240cm³ = 390cm³

What do you mean?
Step-by-step explanation:
I do not understand what ur question is asking
Answer:
<u>Volume = 0.59 m³</u>
<u>Surface Area = 3.93 m²</u>
Step-by-step explanation:
<u>Given :-</u>
- Radius = 0.5 cm
- Height = 0.75 cm
<u>To Find :-</u>
- Volume
- Surface Area
<u>Solving :-</u>
Volume = πr²h
= 22/7 x (0.5)² x 0.75
= 22/7 x 1/4 x 3/4
= 66/112
= 33/56 m³
= 0.59 m³
Surface Area = 2πr (r + h)
= 2 x 22/7 x 0.5 (0.5 + 0.75)
= 22/7 x 5/4
= 110/28
= 55/14 m²
= 3.93 m²
<u>Solution :-</u>
<u>Volume = 0.59 m³</u>
<u>Surface Area = 3.93 m²</u>
