Answer:
396 square inches
Step-by-step explanation:
First we must find the overall surface area of the cake, which will the total area of all of the faces.
The cake is a rectangular prism, meaning the faces are all rectangles and opposite faces will be identical.
As opposite faces are identical, the area of only 3 faces need to be found, and a formula can be crafted:
, where l is length, w is width, and h is height.
For demonstration purposes, the length will be 12 and the width will be 15.
Substituting, we get:
Now, we must subtract the area that is not covered by frosting. As there is only a lack of frosting on the base, we subtract the area of the base.
- You buy a bunch of 12 bananas and pay $6 and want to know how much each banana costs.
- You pull into a gas station where the gas is $2.50 a gallon. You want to know how much you would need to fill up your 35 gallon tank.
- You drove 300 miles to visit your cousin in another state. It takes you 4 hours. You want to know how many miles you drove per hour.
It would be 3.25555555555555........
hope this helps!!
Answer:
Rs. 333
Step-by-step explanation:
Area of the surface of the cuboidal box to be painted = surface area of the cuboidal box - area of the base
✔️Surface area of the cuboidal box = 2(L*W + W*H + L*H)
L = 6 cm
W = 4 cm
H = 2.5 cm
Surface area of the cuboidal box = 2(6*4 + 4*2.5 + 6*2.5) = 2(24 + 10 + 15) = 2(49)
Surface area of cuboidal box = 98 cm²
✔️Area of base = L*W
= 6*4 = 24 cm²
Area of the cuboidal box to be painted = 98 - 24 = 74 cm²
✔️Cost of painting 74 cm² at Rs. 4.50 per cm² = 74 × 4.50 = Rs. 333
