The minimum area is obtained if the box is a cube.
⇒  The lengths of the edges are:

\displaystyle\\
l=  \sqrt[\b3]{32} = \sqrt[\b3]{8 \times 4} = \boxed{2\sqrt[\b3]{4}~~cm}

Help Please<br> Find The Surface Area Of The Prism
snow_lady [41]

Answer:

360 cm^2

Step-by-step explanation:

Find the area of each face of the triangular prism.

Imagine the triangular prism as its net, it is composed with 2 triangular faces (these are tye bases of the prism) and 3 rectangular faces.

Areas of the 2 triangular bases (they are similar triangles):

1/2 x 8 cm x 6 cm = 24 cm^2

24 x 2 = 48 cm^2

Area of the rectangular face:

8 x 13 = 104 cm^2

Area of another rectangular face:

6 cm x 13 cm = 78 cm^2

Area of another rectangular face:

13 cm x 10 cm = 130 cm^2

Add up all the areas of all faces:

48 + 104 + 78 + 130 = 360

So the SA is 360 cm^2

What percentage of 340 is 425?
beks73 [17]

Answer:

125%

Step-by-step explanation:

1. Set up the equation

425/340 = x/100

(percentages are out of 100 so this equation means 425 out of 340 is equal to a number out of 100)

2. Cross multiply

340x = 42500

3. Solve for x

x = 125
