The company Digit Tech designs a new
Marat540 [252]

Answer:

The amount of cardboard Digit Tech needs to

package all 1500 new Smart Phones = 891000 square cm

Step-by-step explanation:

Points to remember:-

<u>Surface area of cuboid</u>

Surface area = 2(lb + bh + lh)

Where, l - Length of cuboid

b - Breadth of cuboid and

h - Height of cuboid

It is given dimensions of cardboard box

12 cm long, 9 cm wide, and 9 cm high.

<u>To find the surface area of box</u>

Here l = 12 cm, b = 9 cm and h = 9 cm

Surface area = 2(lb + bh + lh) = 2[(9*12) + (9*9) + (12 * 9)]

 = 2(108 + 81 + 108) = 2 * 297 = 594 square cm

To find the cardboard required for 1500 box

Total cardboard = 1500 * 594 = 891000 square cm

A child designs a flag in the shape of a rhombus, as shown in the diagram below. Which expression can be used to determine the s
Lady bird [3.3K]
<span>Which expression can be used to determine the side length of the rhombus?

 The answer is the first option: 10/Cos(30°)

 Explanation:

 1. As you can see in the figure attached, there is a right triangle and its hypotenuse (which is represented with the letter "x") is the side you want to calculate. So, you have:

 Cos(</span>α)=Adjacent leg/Hypotenuse
<span>
 </span>α=30°
<span> Adjacent leg=(20 in)/2=10 in
 Hypotenuse=x

 2. When you substitute these values into the formula, you obtain:
</span>
 Cos(α)=Adjacent leg/Hypotenuse
<span> Cos(30°)=10/x

 3. Therefore, you obtain the expression to determine the side length of the rhombus by clearing the hypotenuse "x", as below:

 x=10/Cos(30°)
</span>
