Hey!
------------------------------------------------
We can split this polygon into two rectangular prisms.
Finding the volume is: base * length * height.
~Let's solve for the first prism
5 * 2 * 2 = 20cm³.
~Let's solve for the second prism
8 * 2 * 2 = 32cm³.
~Add both volumes
32 + 20 = 52cm³.
------------------------------------------------
Hence, the volume is 52cm³.

Hope This Helped! Good Luck!
Answer:
21 cm squared
Step-by-step explanation:
The area of a triangle is base times height divided by 2, or
a = base time height/2
The base here is 7cm and the height is 6cm.
7 times 6 is 42.
42 divided by 2 is 21
6 = 3(x - 2)
6 = 3x - 6
3x = 12, x = 4
Solution: D
Since the polys are similar, the following equation of ratios is true:
7/8 = x/3. Cross multiplying produces 21=8x, and so x = 21/8 (answer)
Answer:
71. 8
Step-by-step explanation:
volume of a cylinder = 4/ 3 π r² h
=> 4817 = 4/ 3 × 22/ 7 × 4² × h
=> h = (4817 × 3 × 7)/ (4 × 22 × 4²)
=> h = 71.8
