Answer:

16 cm

Step-by-step explanation:

Let the width be x

The length will be 3 x since the length is three times the width

Perimeter=2(l+w) where l is length and w is width

By substituting 128 cm for perimeter, x for w and 3 x for l then

128=2(3x+x)

128=8x

x=\frac {128}{8}=16

Therefore, the width is 16 cm, the width is 16*3=48 cm

Goryan [66]

Answer:

29 in ^3

Step-by-step explanation:

6 sides

2 of which are smaller than the other 4.

12 x 1/2 x 4 = 4 longer sides

5 x 1/4 x 4 = 2 shorter sides

12 x 1/2 = 6

6 x 4 = 24

5 x 1/4 = 1.25

1.25 x 4 = 5

5 + 24 = 29
