Jade Haney · Answer 1

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

Nathanael Freeman · Answer 2

Step-by-step explanation:

6 times 9 is 54.

54 divided by 2 is 27 volume (recipitor) is 27 for no. 1

6 times 7 is 42

42 divided by 2 is 21 is the recipitor or volume for no. 2

there fore a has a bigger base surface

as base is measured by recipitorial angles

sorry if this isnt the right answer or what u wanted but I know it this way
