Answer:

1) 4 cm

2) 7cm

3) 8 1/6

Step-by-step explanation:

1)

SA = 2(w*l)+2(w*h)+2(l*h)

228 = 2(9*6)+2(9*h)+2(6*h)

2(9*6)+2(9*h)+2(6*h) = 228

30h + 108 = 228

30h = 228-108

30h = 120

h = 4

2)

V = l*w*h

64h = 448

h = 7

3)

V_1 = 0.12V_2

0.98V_2 = \frac{0.98}{0.12}V_1 = \frac{98}{12}V_1 = \frac{49}{6}V_1 = 8\frac{1}{6}
