1) What is the surface area?<br> 1 ft<br> 8 ft<br> 4 ft
WITCHER [35]

Answer:

88 ft^2

Step-by-step explanation:

For a rectangular prism with dimensions 1 ft by 8 ft by 4 ft, there are two opposite faces with dimensions

<em>1 ft by 8 ft, </em>

two opposite faces with dimensions

<em>1 ft by 4 ft, </em>

and two opposite faces with dimensions

<em>4 ft by 8 ft.</em>

We find their area and add them.

SA = 2 * 1 ft * 8 ft + 2 * 1 ft * 4 ft + 2 * 4 ft * 8 ft

SA = 16 ft^2 + 8 ft^2 + 64 ft^2

SA = 88 ft^2

Use the Pythagorean theorem to find the unknown side of the right triangle.
Nesterboy [21]

The length of hypotenuse is 39.

Step-by-step explanation:

Given,

Vertical side = a = 15

Horizontal side = b = 36

Hypotenuse = c

Using pythagorean theorem

a^2+b^2=c^2\\(15)^2+(36)^2=c^2\\225+1296=c^2\\1521=c^2\\c^2=1521

Taking square root on both sides

\sqrt{c^2}=\sqrt{1521}\\c=39

The length of hypotenuse is 39.

Keywords: square root, addition
