Core 3 and 4: Surface Area of Rectangular and Triangular Prisms

Front

What is the formula for the surface area of a rectangular prism?

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

What is the formula for the surface area of a triangular prism?

Back

Surface Area = bh + (perimeter of base * height), where b = base area and height is the height of the prism.

Front

What is the surface area of a square pyramid?

Back

Surface Area = Base Area + (1/2 * Perimeter of Base * Slant Height).

Front

How do you calculate the area of a rectangle?

Back

Area = length × width.

Front

How do you calculate the area of a triangle?

Back

Area = (1/2) × base × height.

Front

What is the total surface area of a box that is 4 cm long, 3 cm wide, and 2 cm high?

Back

Total Surface Area = 2(4*3 + 4*2 + 3*2) = 2(12 + 8 + 6) = 2(26) = 52 cm².

Front

If a rectangular prism has a length of 5 m, width of 3 m, and height of 2 m, what is its surface area?

Back

Surface Area = 2(5*3 + 5*2 + 3*2) = 2(15 + 10 + 6) = 2(31) = 62 m².

Front

What is the surface area of a cube with a side length of 4 cm?

Back

Surface Area = 6 × (side length)² = 6 × 4² = 6 × 16 = 96 cm².

Front

What is the definition of surface area?

Back

Surface area is the total area that the surface of an object occupies.

Front

What is the perimeter of a rectangle with length 6 cm and width 4 cm?

Back

Perimeter = 2(length + width) = 2(6 + 4) = 2(10) = 20 cm.
