Answer:
The surface area of the prism is 252 square units
Step-by-step explanation:
we know that
The surface area of the prism is equal to

where
B is the area of the base of the prism
P is the perimeter of the base
L is the length or the height of the prism
step 1
Find the area of the triangular base B
The area of triangular base B is

The perimeter of the triangular base P is

we have

substitute the values in the formula

For the square part- 10*10=100sq in
For the half circle
r=5
5*5=25
3.14*25=78.5
There's no problem so we can't answer it
PV = nRT
P: pressure of gas
V: volume of gas
n: number of moles of gases
R: constant
T: thermodynamic temperature of gas
All the statements apply
Hope it helped!
