Answer:

272 square inches

Step-by-step explanation:

Given: A cereal box is 8 inches by 2 inches by 12 inches.

To find: Surface area of the cereal box.

Solution:

The dimensions of the cereal box are 8 inches by 2 inches by 12 inches.

Let the length be 8 inches, width be 2 inches, and height be 12 inches.

Here, we need to find the total surface area of the cereal box.

The cereal box is in the shape of a rectangular prism.

The total surface area of the rectangular prism can be calculated as

= 2(\text{length} \times \text{width} + \text{width} \times \text{height} + \text{length} \times \text{height})

= 2(\text{8} \times \text{2} + \text{2} \times \text{12} + \text{8} \times \text{12})

=2(16+24+96)

=2\times136

=272

So, the surface area of the cereal box is 272 square inches.

Need help rn please?/..Thank you. Multiple step equation
liubo4ka [24]

Answer:

The answer (using BEDMAS) is 27

Step-by-step explanation:

The equation 9 x [(18+2) ÷ 5 - 1] is solved using BEDMAS or PEDMAS

First solve the smaller bracket

18 + 2 = 20

So then it becomes 9 x [20 ÷ 5 - 1]

Do the division inside the bracket next

20 ÷ 5 = 4

Then it becomes 9 x [4 - 1]

Do then subtraction within the bracket

4 - 1 = 3

Then it becomes 9 x 3

Finally solve 9 x 3 which equals 27

The length of a rectangle is three more than its width. The perimeter is 86cm. Find the length and width of the rectangle. Write
elena-s [515]
P=2(l+w)
Substitute width plus 3 for length
Remember order of operations: multiply before adding

86=2((w+3) + w)
86=2w+6+2w
86=4w+6
80=4w
20=w
23=w+3=l

Check the answer
86=2((w+3) + w)
86=2((20+3)+20
86=2(23+20)
86=46+40
86=86
