A box has the shape of a rectangular prism with height of 28 cm. If the height is increased by 0.2 by how much does the surface area of the box increase?

Answers

Answer:

The surface area of the box increase by 0.2P (the perimeter of the base multiplied by 0.2)

Step-by-step explanation:

we know that

The surface area of the rectangular prism is equal to

SA=2B+Ph

where

B is the area of the base

P is the perimeter of the base

h is the height of the prism

If the height is increased by 0.2

then

SA=2B+P(h+0.2)  

SA=2B+Ph+P(0.2)  

The surface area of the box increase by 0.2P (the perimeter of the base multiplied by 0.2)

Final answer:

The overall change in surface area when the height of a rectangular prism is increased by 0.2 cm can be calculated with the formula 0.4w + 0.4l.

Explanation:

In this question, we are looking at the surface area of a box that is a rectangular prism and how it will change if the height of the box is increased by 0.2 cm. The surface area of a prism is given by the formula 2lw + 2lh + 2wh, where l, w and h are the length, width and height respectively.

Now, if the height is increased by 0.2 cm, the difference in the surface area will be 2lw (because there are two ends with area lw that do not change) plus the change in the area of the sides. The sides' areas will increase by 2w x 0.2 and 2l x 0.2 respectively (since we have two opposing sides that both increase by 0.2 cm in height).

Therefore, the overall change in surface area when the height is increased by 0.2 cm is simply the sum of these two parts, which is 2w x 0.2 + 2l x 0.2. This can also be simplified to 0.4w + 0.4l.

The area of a rectangle is 240 in squared. the ratio of the length to the width is 5 : 3. find the length and the width.

Answers

hey user!!

your answer is here...

given the ratio between the Length and breadth (width) of the rectangle is 5 : 3

let the Length and breadth of the rectangle be 5x and 3x approximately.

area of the rectangle = 240in²

therefore l × b = 240in²

==> 5x × 3x = 240in²

==> 15x² = 240in²

==> x² = 240/15

==> x² = 16

==> x = √16

==> x = 4in

hence, length of the rectangle = 5x = 5 × 4 = 20in

breadth of the rectangle = 3x = 3 × 4 = 12in

cheers!!
