Colin stacks 3 snowballs on top of each other to make a snowman. The snowballs are 7/10 meter, 1/2meter, and 38 centimeters tall. What is the total height of the snowman in centimeters?

158cm

Step-by-step explanation:

Data obtained from the question. This includes:

Height of first snow ball (H1) = 7/10m

Height of 2nd snow ball (H2) = 1/2m

Height of 3rd snow ball (H3) = 38cm

Total height of snow man (HT) = ?

Next we shall covert from m to cm.

This is illustrated below:

For the first snow ball

1m = 100cm

7/10m = 7/10 x 100 = 70cm

For the 2nd snow ball:

1m = 100cm

1/2m = 1/2 x 100 = 50cm

Now we can obtain the height of the snow man as follow:

Height of first snow ball (H1) = 70cm

Height of 2nd snow ball (H2) = 50cm

Height of 3rd snow ball (H3) = 38cm

Total height of snow man (HT) = ?

HT = H1 + H2 + H3

HT = 70 + 50 + 38

HT = 158cm

Therefore the height of the snow man in cm is 158cm
