TEK 6.8D Area and Volume

Front

What is the formula for finding the area of a triangle?

Back

A = 1/2(base x height)

Front

What is the area of a triangle with a base of 80 units and a height of 25 units?

Back

A = 1/2(80 x 25) = 1,000 square units

Front

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

Back

V = length x width x height

Front

If a rectangular prism has a length of 10 ft, a width of 5 ft, and a height of 2 ft, what is its volume?

Back

V = 10 x 5 x 2 = 100 cubic feet

Front

What is the difference between area and volume?

Back

Area measures the surface of a shape in square units, while volume measures the space inside a 3D object in cubic units.

Front

What is the area of a rectangle with a length of 10 ft and a width of 5 ft?

Back

A = length x width = 10 x 5 = 50 square feet

Front

What is the formula for finding the area of a parallelogram?

Back

A = base x height

Front

If a parallelogram has a base of 12 cm and a height of 5 cm, what is its area?

Back

A = 12 x 5 = 60 square centimeters

Front

What is the formula for finding the area of a circle?

Back

A = πr² (where r is the radius)

Front

If a circle has a radius of 3 cm, what is its area?

Back

A = π(3)² = 28.27 square centimeters (using π ≈ 3.14)
