Mathematics

Answer:

Pretty sure its 7.5 units²

Step-by-step explanation:

5·3=15÷2=7.5

Doing area with triangles is kind of the same as rectangle, just do base × height. But then divide it by two.

For example: base=3, height=7. With rectangles it would be 21 units².

But with triangles it would be 3·7=21 divided by 2, it would be 10.5 units²

I need to find the surface area of the square pyramid! <br> (I know I'm stupid lol)
pogonyaev

Answer:

L = 260 cm^2

Step-by-step explanation:

height h = 12 cm

slant height s = 13 cm

side length a = 10 cm

lateral edge length e = 13.928388277184 cm

1/2 side length r = 5 cm

volume V = 400 cm^3

lateral surface area L = 260 cm^2

base surface area B = 100 cm^2

total surface area A = 360 cm^2

Genda: h = height

s = slant height

a = side length

e = lateral edge length

r = a/2

V = volume

L = lateral surface area

B = base surface area

A = total surface area
