Surface Area Rect. and Tri. Prisms

Front

What is a Rectangular Prism?

Back

A 3D solid with six rectangular faces, where opposite faces are equal in area.

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 + l(a + b + c), where b = base, h = height of the triangle, l = length of the prism, a, b, c = sides of the triangle.

Front

What are the units for Surface Area?

Back

Surface area units should be squared (e.g., cm², m²).

Front

How do you find the Surface Area of a rectangular prism with dimensions 9 m (length), 10 m (height), and 12 m (width)?

Back

Surface Area = 2(9*10 + 9*12 + 10*12) = 636 m².

Front

What is a Triangular Prism?

Back

A 3D solid with two triangular bases and three rectangular faces.

Front

What is the difference between Surface Area and Volume?

Back

Surface Area measures the total area of the surface of a 3D object, while Volume measures the space inside the object.

Front

What is the Surface Area of a triangular prism with a base area of 40 cm², height of 10 cm, and length of 5 cm?

Back

Surface Area = 40 + 5(10 + 8 + 6) = 140 cm².

Front

What is the Surface Area of a rectangular prism with dimensions 5 cm, 4 cm, and 3 cm?

Back

Surface Area = 2(5*4 + 5*3 + 4*3) = 62 cm².

Front

What is the Surface Area of a cube with side length 6 cm?

Back

Surface Area = 6 * (6 cm)² = 216 cm².
