A cube with sides 5 inches, and a pyramid with base edges 5 inches. What is the height, so that the volume of the cube and the p
Ostrovityanka [42]

<u>1</u><u>5</u><u> </u><u>inches</u> is the height of the pyramid

Step-by-step explanation:

The volume of a cube is a³

Given <em>a</em> = 5 inches

→ Volume = a³

= 5³

= 5×5×5

= <u>125 in²</u>

The volume of a pyramid is \frac{1}{3} {a}^{2}h

Given a = 5 inches , h = height of pyramid

=  >  \frac{1}{3} {a}^{2} h

=  >  \frac{1}{3}(5)^{2}h

=  >  \frac{1}{3} \times 25 \times h

=  >  \frac{25}{3}h

then,

125 =  \frac{25h}{3}

=  > 25h = 125 \times 3

=  > 25h = 375

=  > h =  \frac{375}{25}

=  > h = 15

Hence, the height of pyramid is <u>1</u><u>5</u><u> </u><u>inches</u>
