Answer:
336 cm^2
Step-by-step explanation:
Well theres not exactly a formula, I jsut solve the 3 faces and then double it all since 2 are the same for each except for 1 so the first side is the 10X12 one. that would give you 60 and then you double that and get 120 since 2 same faces.
The next one the 6X13 one is just a sideways rectangle, a=lw and that would be 78. Two faces same side double 78 and get 156.
Now the final side is the bottom which is jsut 10X6. a=lw and that would eqaul 60. No need to double since thats the only side that doesn’t have a duplicate. Add all your result up and you would get
336 cm^2
The word "difference" means subtract (-)
29 equals 29
A number equals w
So, your answer would be: 29 - w
<h2>
The required value of x is equal to 2.</h2>
Step-by-step explanation:
We have,

To find, the value of x in the given equation = ?
∴ 
By crossmultiplication, we get
3(3x) = x + 16
⇒ 9x = x + 16
⇒ 9x - x = 16
⇒ 8x = 16
⇒ x = 
⇒ x = 2
∴ The value of x = 2
Thus, the required value of x is equal to 2.
The prism with the pentagonal base's volume is 585 cm³.
Step-by-step explanation:
Step 1:
The prism has a pentagonal base.
The volume of a prism with a pentagonal base, 
In the formula to determine the prism's volume, in the question, it is given that
is equal to 45 cm².
Step 2:
So if we substitute
in
we get,

The value of h for the given prism is 13 cm, so
cm³.
The prism's volume is 585 cm³.
