Finding Missing Dimensions in Prisms

The video tutorial guides students through solving a homework problem involving finding a missing length of a rectangular prism when given the volume and two other dimensions. The teacher emphasizes the importance of drawing a picture to visualize the problem. The process involves multiplying the known dimensions and then dividing the result from the volume to find the missing length. The tutorial concludes with a recap of the steps: multiply the two known dimensions and divide the result from the volume.

What is the first step in solving the problem of finding a missing length of a rectangular prism?

• Draw a picture of the prism

• Calculate the area of the base

• Estimate the missing length

• Find the perimeter of the prism

When given the width and height of a rectangular prism, what should you do next?

• Add the dimensions together

• Multiply the dimensions together

• Subtract the dimensions

• Divide the dimensions

How do you determine where to place the decimal point after multiplying two decimal numbers?

• Use a calculator to find the position

• Ignore the decimal places

• Place it at the end of the number

• Count the total number of decimal places in both numbers

What is the next step after finding the product of the known dimensions?

• Divide the volume by the product

• Subtract the product from the volume

• Add the product to the volume

• Multiply the volume by the product

Why is it important to move the decimal point when dividing by a decimal number?

• To simplify the multiplication

• To convert the divisor into a whole number

• To increase the accuracy of the result

• To make the division easier

What should you do if the divisor does not fit into the dividend during division?

• Start over with a new problem

• Bring down the next digit

• Use a smaller divisor

• Add more digits to the dividend

How many times does 896 go into 2240?

• Four times

• Once

• Twice

• Three times

What is the final step in finding the missing length of the rectangular prism?

• Verify the result by recalculating

• Ensure the remainder is zero

• Add all dimensions together

• Check the result with a calculator

What is the missing length of the rectangular prism in the example?

• 3.2 feet

• 2.8 feet

• 8.96 feet

• 2.5 feet

What are the two main steps in solving for the missing dimension?

• Multiply the two dimensions and add to the volume

• Multiply the two dimensions and divide from the volume

• Add the two dimensions and multiply by the volume

• Subtract the two dimensions and divide by the volume
