Find the surface area of a pyramid, explain in detail. square bass of 230 meters by 230 meters; height of 140 meters

SA = 52900 + 2300√1313 m²

Step-by-step explanation:

The equation of the surface area of a pyramid:

SA = area of base + 0.5 * perimeter of base * slant height

1. Area of the base: Since it's a square base, 230² m² = 52900 m²

2. Perimeter of the base: The base is square, 230*4 m = 920 m

3. Slant height: 115² + 140² = h² --> h² = 32825 --> h = 5√1313 m

Plug in: SA = 52900 + 0.5 * 920 * 5√1313

Multiply: SA = 52900 + 2300√1313 m²

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
