A standard step height is 8". If there are 6 steps, how high is the top landing in<br> feet? *
DENIUS [597]

Answer:

4 feet

Step-by-step explanation:

If the standard step height is 8", this means that every step in a staircase will have a height of 8". If there are a total of 6 steps in the staircase we can simply multiply the number of steps by the height of each individual step to get the total height of the top landing. Like so...

6 * 8 = 48"

Finally, we can see that the top landing for the stairs is 48". We can turn this into feet by dividing by 12 since there are 12" in a foot

48 / 12 = 4 feet

Therefore, the top landing will have 4 feet ( or 48 inches)
