Question

Which of these formulas could not be used to calculate the surface area of this figure?

a square pyramid

surface area equals base squared plus 2 times base times slant height

surface area equals pi times radius squared plus pi times radius times slant height

surface area equals base plus lateral area

surface area equals base squared plus 4 times the quantity one-half times base times slant height

Answer 1

C

Answer 2

surface area equals base plus lateral area?

Answer 3

Who knows? You didn't post a figure.

Answer 4

The figure is a square pyramaid.

Answer 7

give me a sec yeah? @alysssaah7

Answer 8

Ok!

Answer 9

okay well do you know the original formula of surface area for a square pyramid?

Answer 10

no... this is the only information i got.. :(

Answer 11

okay well ill find something so hold on(:

Answer 12

okay surface area of a square pyramid = 2bs + b^2

Answer 13

b = base
s = slant height

Answer 14

another is SA = s2 + 2 × s × l

Answer 15

SA = surface area
s = base
l = slant height

Answer 16

so that crosses out the first one

Answer 17

HINT: lateral plus (2 times base) equals area

Answer 18

so its C

Answer 19

No its not. i have it in my notes that u could solve it with that.
