Step-by-step explanation:
a rectangular prism (like this brick) has the same basic structure as a cube (like a die) : it has 6 sides.
while a die has 6 equal sides, a rectangular prism has 3 pairs of equal sides :
top and bottom
left and right
front and back
all we have to do is calculate the areas of the 6 rectangles and add them up. that's it.
your remember, the area of a rectangle is
length × width
in our case we have
top and bottom : 2.5×11.5 × 2 = 28.75×2 = 57.5 in²
left and right : 2.5×5 × 2 = 12.5×2 = 25 in²
front and back : 11.5×5 × 2 = 57.5×2 = 115 in²
so, the total surface area of the whole block is
57.5 + 25 + 115 = 197.5 in²
F(0)= -4(0)+9
F(0)= 0+9
F(0)=9
Answer:Not true
Step-by-step explanation:12 is divisible by 3, and 12 is even.
Answer:
well, first you'd do 13 x 4.
13x4= 52.
then do 52 times 2.
52x2= 104.
- 104 plus 13= there's the answer.
