What is the length of the diagonal of a cube of 4 inches

BartSMP [9]

First find the length of the diagonal of a square of side 4 inches:

d^2 = 4^2 + 4^2 = 2*4^2 = 32. Then the diagonal of the cube has length

sqrt( 32 + 4^2) = sqrt(32+16) = sqrt(48) = 4sqrt(3).

Answer:

B) 10 cm

Step-by-step explanation:

Hello!

We can use the Pythagorean theorem to solve for the hypotenuse.

Formula: $a^2 + b^2 = c^2$

a = leg
b = leg
c = hypotenuse

We can plug in the values for each leg to solve for the hypotenuse.

<h3>Solve for c</h3>

$a^2 + b^2 = c^2$
$6^2 + 8^2 = c^2$
$36 + 64 = c^2$
$100 = c^2$
$\sqrt{100} = \sqrt{c^2}$
$10 = c$

The answer is Option B: 10 cm
