The first thing we must do for this case is to find the surface area of the rectangular prism.
 We have then:
 A = 2 * (l * h) + 2 * (h * w) + 2 * (w * l)
 Where,
 w: width
 l: long
 h: height
 Substituting values we have:
 A = 2 * (10 * 8) + 2 * (8 * 8) + 2 * (8 * 10)
 A = 448 in ^ 2
 Answer:
 
the least amount of wrapping paper needed to wrap the gift box answer is:
 
A = 448 in ^ 2

To find the least amount of wrapping paper needed, you will find the surface area of the rectangular prism.

These are the areas of all the faces.

Top/Bottom: 8 x 8 = 64 in.²
Front/Back. 8 x 10 = 80 in.²
Left Side/Right Side: 8 x 10 = 80 in.²

(64 x 2) + (80 x 2) + (80 x 2) =
448 in.²

The least amount of wrapping paper needed is 448 in.².

The dimensions of a room are 4.2m by 6m. On a plan, the longer side is equal to 4 cm. What is the length of the shorter side on
Fiesta28 [93]

Answer: Length of shorter side is 2.8 cm.

Explanation:

Since we have given that

Dimensions of a room are given by

4.2\ m\times 6\ m

On a plan,  the longer side = 4 cm

As we know that the ratio of original room is equal to ratio of plan room

So,

\frac{4.2}{6}=\frac{x}{4}\\\\4.2\times 4=6x\\\\16.8=6x\\\\\frac{16.8}{6}=x\\\\2.8=x

So, length of shorter side is 2.8 cm.

Find the distance (-4,6) and (3,-7)
forsale [732]

Answer:

Distance ≈ 14.8

Step-by-step explanation:

<u>Calculate the distance (d) using the distance formula</u>

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 4, 6) and (x₂, y₂ ) = (3, - 7)

Hope this helps!!!!

-11≤x

Step-by-step explanation:

Given

6.7 ≥ -0.2x +4.5----------------collect like terms

6.7-4.5 ≥ -0.2x--------------divide by -0.2 both sides

2.2/-0.2 ≥ -0.2/-0.2x-------------------reverse the sign

-11 ≤ x
