The surface area of the rectangular prism is 2(lw + wh + lh). A rectangular prism has six rectangular faces.
<h3>What is the area of a rectangle?</h3>
The area of a rectangle with length and width is
Area = length × width
I.e., A = l × w sq. units
<h3>How to calculate the area of the rectangular prism?</h3>
A rectangular prism has six rectangular faces and the length 'l', width 'w', and height 'h'.
So, the areas of each face are as follows:
A(R1) = l × w
A(R2) = l × h
A(R3) = w × h
A(R4) = l × w
A(R5) = l × h
A(R6) = w × h
Thus, the area of the prism = sum of areas of all the faces
⇒ Area of the prism = lw + lh + wh + lw + lh + wh
⇒ A = 2lw + 2lh + 2wh
⇒ A = 2(lw + lh + wh)
Therefore, the area of the rectangular prism is A = 2(lw + lh + wh).

Answer:
x=4. y= 7/2----3.5
Step-by-step explanation:
for B the answer could also he m=0, b=7/2 if you're looking for the function
if you want the alt version it could also be y=3 1/2/y=3.5
Answer: In order to find what the coordinates of B are is by trying to know how we got to (-2,0) of line AB. You have to subtract 3 from A coordinate x which is 1,it will give you -2, and you have to subtract 1 from A coordinate y which is 1,it will give you 0.
Answer:
11253.76
Step-by-step explanation:
To find the volume of a cylinder we must utilise the volume of cylinder formula which is
→ Volume of cylinder = π × r² × h
Where 'r' is the radius and 'h' is the height so let's start substituting in the values,
→ Volume of cylinder = π × r² × h
⇒ Substitute in 3.14 for π, 14 for 'h' and 16 for 'r'
→ Volume of cylinder = 3.14 × 16² × 14
⇒ Simplify
→ Volume of cylinder = 11253.76
So a cylinder has a height of 14 millimetres and a radius of 16 millimetres has a volume of cylinder 11253.76 inches³
