Answer:
23
Add positive 14 and 9 to get 23
14 + 9 = 23
-14 + 23 = 9
Step-by-step explanation:
We have,
l =5ft
b=2ft
h=3ft

v = (l*b*h)
v = (5*2*3)ft
v = (30)ft
.•. v = 30ft

Step-by-step explanation:
Given:
A prism with height 5 cm and equilateral triangular base with side 2 cm.
To find:
The total surface area of the prism.
Solution:
Area of an equilateral triangle is:

Where, a is the side length.
Putting
, we get




The base and top of the prism are congruent so their area must be equal.
The lateral surface area of the prism is:

Where, P is the perimeter of the base and h is the height of the prism.
The lateral surface area of the prism is:



Now, the total surface area is the sum of areas of bases and lateral surface area.




Therefore, the total surface area is 33.46 cm².
Answer:
113.1cm
Step-by-step explanation:
area=
r²
r= half the diameter r=6
a=
6²
a=
36
a=113.1 cm
