Question

Regular pyramid
B=
P=
H=
l=
LA=
SA=
V=

Answer 1

Perimeter of base=4(4)=16m

Area of base=4²=16m²

Height=6m

Slant height=6.3m

Lateral surface area=4(1/2(4)(6.3))=8(6.3)=50.54m²

Total surface area=50.54+16=66.54m²

Volume=a²h/3=4²/(6)/3=16(2)=32m³

Answer 2

B (Base surface area) = 16
`m^(2)`

P (Perimeter of the base) = 16 m

H (Height) = 6 m

L (Not sure what L means. I assume it's the slant height??) = 6.32 m

LA (I assume lateral surface area) =
`50.59 m^(2)`

SA (I assume total surface area) =
`66.59 m^(2)`

V (volume) =
`32 m^(3)`

Explanation:

Sorry if anything is wrong. It would be more helpful to put the names, instead of acronyms.
