Surface area of square pyramids

Front

What is the formula for calculating the surface area of a square pyramid?

Back

The surface area (SA) of a square pyramid is given by the formula: SA = B + (1/2) * P * l, where B is the area of the base, P is the perimeter of the base, and l is the slant height.

Front

What is the area of the base of a square pyramid if the side length is 5 cm?

Back

The area of the base (B) is calculated as B = side^2. For a side length of 5 cm, B = 5^2 = 25 cm².

Front

How do you calculate the perimeter of the base of a square pyramid?

Back

The perimeter (P) of the base of a square pyramid is calculated as P = 4 * side, where 'side' is the length of one side of the square base.

Front

What is the slant height of a square pyramid?

Back

The slant height (l) is the distance from the apex (top point) of the pyramid to the midpoint of one of the sides of the base.

Front

If a square pyramid has a base side length of 4 m and a slant height of 3 m, what is its surface area?

Back

First, calculate the area of the base: B = 4^2 = 16 m². Then, calculate the perimeter: P = 4 * 4 = 16 m. Now, use the formula: SA = B + (1/2) * P * l = 16 + (1/2) * 16 * 3 = 16 + 24 = 40 m².

Front

What units are used when calculating the surface area of a square pyramid?

Back

The units for surface area are square units, such as square centimeters (cm²), square meters (m²), square yards (yd²), or square inches (in²), depending on the measurement system used.

Front

What is the relationship between the height and the slant height of a square pyramid?

Back

The height (h) and the slant height (l) of a square pyramid are related through the Pythagorean theorem: l² = h² + (side/2)².

Front

How does the surface area of a square pyramid change if the base side length is doubled?

Back

If the base side length is doubled, the area of the base increases by a factor of four (since area is proportional to the square of the side length), and the perimeter also doubles, affecting the overall surface area calculation.

Front

What is the significance of the apex in a square pyramid?

Back

The apex is the top point of the pyramid where all the triangular faces meet, and it is crucial for determining the slant height and overall shape of the pyramid.

Front

How do you find the surface area of a square pyramid with a given height?

Back

To find the surface area with a given height, first calculate the slant height using the Pythagorean theorem, then use the surface area formula: SA = B + (1/2) * P * l.
