Front

What is estimation in mathematics?

Back

Estimation is the process of finding an approximate value or quantity based on reasonable assumptions or calculations, rather than an exact answer.

How do you convert years to seconds?

Back

To convert years to seconds, multiply the number of years by 365 (days), then by 24 (hours), then by 60 (minutes), and finally by 60 (seconds). For example, 25 years = 25 x 365 x 24 x 60 x 60 = 788,400,000 seconds.

What is the formula for calculating the volume of a rectangular prism?

Back

Volume = length × width × height.

Front

How do you estimate the number of people in a crowd given area and space per person?

Back

Estimate the total area occupied by the crowd, then divide by the area occupied by one person. For example, if the area is 1.8 miles long and 7 feet deep on both sides, convert to square feet and divide by the area per person.

Front

What is the significance of rounding in estimation?

Back

Rounding simplifies numbers to make calculations easier and quicker, especially when an exact number is not necessary.

Front

How do you calculate the number of items that fit in a given volume?

Back

Divide the total volume of the space by the volume of one item. For example, if a room has a volume of 3,456 cubic feet and a box has a volume of 128 cubic feet, then 3,456 / 128 = 27 boxes.

What is the relationship between time and frequency in blinking?

Back

Frequency is the number of occurrences of a repeating event per unit time. For example, if Dory blinks 2 times every 10 seconds, her blinking frequency is 0.2 blinks per second.

Front

How do you calculate the total number of blinks in a given time period?

Back

Multiply the frequency of blinks by the total time in seconds. For example, if Dory blinks 2 times every 10 seconds, in 2 years (63,072,000 seconds), she blinks 12,614,400 times.

Front

What is the formula for calculating the total number of items in multiple boxes?

Back

Total items = (number of boxes) × (items per box). For example, if there are 18 bushels in a box and 6 bananas per bushel, then total bananas = number of boxes × 18 × 6.

Front

How do you convert feet to inches?

Back

To convert feet to inches, multiply the number of feet by 12. For example, 2 feet = 2 x 12 = 24 inches.
