Question

Please help meeeeeeeeeeeeeee

Answer 1

multiply it by 2

Explanation:

Answer 2

1) 4 cm

2) 7cm

3) 8 1/6

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 = (0.98)/(0.12)V_1 = (98)/(12)V_1 = (49)/(6)V_1 = 8(1)/(6)`
