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
Answer:4x+32+5x-15
Step-by-step explanation: that’s the simplified equation, you would just have to distribute the 4 to its own equation and the 5 into its own equation.. but i think the second part of ur question is missing..
we have chicken broth in cylindrical can.
we have given the height radius of cylindrical can.
h=10cm r=10 cm .
and she have 6cm broth height in the tin that means she had used 4 cm of height of broth .
now we need to find volume of two cylinder with h=10 cm and 6cm
and we need to find the difference between the volumes .
volume1=
volume 2=
volume used =volume 1-volume2=3140-1884=1256cm^3 is used
