Question

determine how many boxes of flooring will be needed to cover a 10 feet by 12 feet room if 10% waste is assumed. first, find the area of the room. the area of the room is __ square feet. remember that area of a rectangle is length times width. next, calculate the total square footage of flooring including the 10% waste. hint: multiply the area of the floor by 1.10. the total area including 10% waste is __ square feet. lastly, calculate the number of boxes of flooring that you will need to buy to ensure that you have enough to cover the floor including at least 10% waste. each box has 10 square feet. round up to nearest whole number. question 18 (5 points) stride length is the distance between the initial contact points of the same foot when taking two steps, one with each foot. for example, its the distance from the back of the heel of one foot a the start of a step to the back of the heel of the same foot at the end of the step. refer to the picture as a reference. if your right step length is 1.25 feet and your left footstep is also 1.25 feet, what is your stride length. give a numerical answer. do not put units. using the previous stride length, you want to determine the length of one of the hallways at your school. if it takes you 8.5 strides to walk the entire hallway, what is the length of the hallway? give an unrounded number answer. do not include units.

Explanation:

Step1: Calculate room area

$10\times12 = 120$

Step2: Calculate area with waste

$120\times1.10=132$

Step3: Calculate number of boxes

$\lceil\frac{132}{10}
ceil = 14$

Step4: Calculate stride length

$1.25 + 1.25=2.5$

Step5: Calculate hallway length

$2.5\times8.5 = 21.25$

Answer:

120
132
14
2.5
21.25
