V = LWH

V = (100 cm)(50 cm)(4 cm) = 20,000 cm³ . . . volume

The mass is ...

(20,000 cm³)(2.7 g/cm³) = 54,000 g = 54 kg

$\overline{y}$ (prounounced "y bar") is the mean of the y values

Add up the y values to get
5+7+10+15+18 = 55

Then divide by 5 (because there are five y values) to get
55/5 = 11

Therefore,
$\overline{y} = 11$

The answer is choice C
