Edge length = 63 feet

Volume = (length) x (width) x (height)

Volume = (63 ft) x (63 ft) x (63 ft) = (63 ft)³ = 250,047 ft³ .
=====================================

1 yard = 3 ft
63 ft = 21 yards

Volume of the cube = (21 yd) x (21 yd) x (21 yd) = (21 yd)³ = 9,261 yd³
======================================

A slightly different way:

1 yard = 3 ft
1 yard³ = (3 ft)³ = 27 ft³

Volume of the cube = (250,047 ft³) x (1 yd³/27 ft³) = 250,047/27 = 9,261 yd³

Montano1993 [528]

Answer:

Depends on the data

Step-by-step explanation:

You need to arrange all of the data from the chart in numerical order.

Then figure out which number/numbers are in the middle of the data line.

If it was just one number that is the median. If two numbers were in the middle add them together then divide by two, that is your median.
