Pyramid A has a square base with side lengths of 6 meters, and 4 triangular sides with a base of 6 meters and height of 7 meters. Pyramid B has a rectangular base with length of 6 meters and height of 4 meters, and 4 triangular sides. 2 triangular sides have a base of 6 meters and height of 9 meters. The other 2 triangular sides have a base of 4 meters and height of 9.3 meters. Which pyramid has the greatest surface area? Pyramid

Pyramid A has greater surface area

Step-by-step explanation:

Pyramid A

A=lw+l√((w /2)²+h²)+w√((l /2)²+h²)

l=w= 6 m

h= √7²-3³= √40 ≈ 6.33 m

A≈ 120 m²

Pyramid B

A=lw+l√((w /2)²+h²)+w√((l /2)²+h²)

l= 6 m

w=4 m

h= √9²-2³= √73 ≈8.54 m

A≈ 112.83 m²

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

they aren't great and cause destruction, idk man
