a) Volume (V) of a cube = side (x)³ → V = x³ → 1728 = x³ → 12 in = x

b) Area (A) = x² → A = (12)² → A = 144 in²

c) Surface Area (SA) of a cube = 6A → SA = 6(144) → SA = 864 in²

d) 864 in² · (\frac{1 ft}{12 in})² = \frac{864}{144} = 6 ft²

GREYUIT [131]

Answer:  31) d     32) c

<u>Step-by-step explanation:</u>

31)

A = {1, 3, 5, 15}

B = {2, 3, 5, 7}

A ∪ B = {1, 2, 3, 5, 7, 15}

C = {2, 4, 6, 8}

(A ∪ B) ∩ C = {1, 2, 3, 5, 7, 15} ∩ {2, 4, 6, 8} = {2}

<em>2 is the only number in both sets</em>

32)

The pattern is: reflection, add symbol, ..., reflection, add symbol.

The last image shown is: add symbol

So the next image will be: reflection (flipped to the left)
