Q & A

What is the correct method for calculating the number of cubes in the given shape?

To calculate the number of cubes in the shape, you multiply the length, width, and height. The length and height are both 10, and the width is 1. So, the calculation is 10 * 10 * 1 = 100, then add the extra cubes as shown, which gives a total of 107.

How do you read the number 416 correctly in the given script?

The number 416 is read as 'four hundred sixteen.' In the script, it is confirmed that the correct answer is C, 416.

What is the place value of the digit 1 in the number 671?

The place value of the digit 1 in the number 671 is in the hundreds place, which represents 100.

How do you identify the correct order of numbers from smallest to largest?

To order numbers from smallest to largest, look at the first digits. For example, 461 comes first, followed by 559, and 702 is the largest, so the correct order is 461, 559, 702.

What is the correct comparison symbol between 702 and 712?

The correct comparison symbol between 702 and 712 is '<', meaning 702 is smaller than 712.

How do you calculate the total number of marbles in two boxes?

To calculate the total number of marbles, simply add the marbles in the first box (42) and the second box (29). 42 + 29 = 71.

How do you calculate the number of male participants in a competition?

To find the number of male participants, subtract the number of female participants (22) from the total number of participants (46). 46 - 22 = 24 male participants.

How many donuts did Nara buy if each box contains 10 donuts and she bought two boxes?

Nara bought 2 boxes, with 10 donuts in each box. Therefore, the total number of donuts is 10 * 2 = 20.

If Pak Mamad buys 10 goats and puts them into two pens equally, how many goats are in each pen?

To find out how many goats are in each pen, divide the total number of goats (10) by the number of pens (2). 10 / 2 = 5 goats per pen.

How do you calculate the difference in the number of candies between Nisa and Olive?

To calculate the difference in the number of candies, subtract the number of candies Olive has (27) from the number Nisa has (53). 53 - 27 = 26, so the difference is 26.
