Lesson 2.5 Day 5 Assignment (Geo H)

Front

What is surface area?

Back

Surface area is the total area that the surface of a three-dimensional object occupies. It is measured in square units.

Front

How do you calculate the surface area of a rectangular prism?

Back

To calculate the surface area of a rectangular prism, use the formula: SA = 2(lw + lh + wh), where l is length, w is width, and h is height.

Front

What is the formula for the surface area of a cylinder?

Back

The surface area of a cylinder is given by the formula: SA = 2πr(h + r), where r is the radius and h is the height.

Front

What is volume?

Back

Volume is the amount of space that a three-dimensional object occupies, measured in cubic units.

Front

How do you calculate the volume of a rectangular prism?

Back

The volume of a rectangular prism is calculated using the formula: V = lwh, where l is length, w is width, and h is height.

Front

What is the formula for the volume of a cylinder?

Back

The volume of a cylinder is calculated using the formula: V = πr²h, where r is the radius and h is the height.

Front

What does it mean to round to the nearest hundredth?

Back

Rounding to the nearest hundredth means adjusting a number to two decimal places, where the second decimal place is the hundredth.

Front

If the surface area of a figure is 132 yd², what does this represent?

Back

This represents the total area of the outer surface of the figure, measured in square yards.

Front

What is the significance of units in surface area and volume calculations?

Back

Units indicate the measurement scale and ensure that calculations are consistent and meaningful, such as square units for area and cubic units for volume.

Front

How do you find the surface area of a sphere?

Back

The surface area of a sphere is calculated using the formula: SA = 4πr², where r is the radius.
