How to find the total surface area of a rectangular prism?

1 answer:

3 0

If the length is taken as l , height is taken as h and breadth is taken as b . then

Area of the rectangular prism= 2( (l*b) + (b*h) + (h*l) )

hope that helps

FIND Y OF THIS CIRCLE.

kotegsom [21]

Answer:

y = 116

Step-by-step explanation:

The central angle is double any inscribed angle that intercepts the same arc.

Inscribed angle HGF intercepts arc HF, so central angle HOF will be double the value of HGF.

2×58° = 116° = y°

y = 116

A suitcase measures 24 inches long and -8 i aches high. What is the diagonal length of the suitcase? (Pythagorean Theorem)

BartSMP [9]

Answer:

Diagonal Length = $8\sqrt{10}$ inches

Step-by-step explanation:

The suitcase is a rectangle with one side being 24 and another side being 8.

The diagonal is the line through the middle connecting two opposite corners.

If we draw the diagonal, it creates a triangle with one leg being 24 and another being 8.

The diagonal is the "hypotenuse" of the triangle.

Now, the pythagorean theorem:

leg^2 + another leg^2 = hypotenuse^2

So, we substitute the values known and find the hypotenuse (which is length of the diagonal). Shown below:

$24^2+8^2=h^2\\640=h^2\\h=\sqrt{640}\\h=\sqrt{64*10}\\h=\sqrt{64}\sqrt{10}\\h=8\sqrt{10}$

We have written the answer in exact form (with radical in simplified term).

We also use the radical property $\sqrt{a*b}=\sqrt{a}\sqrt{b}$
