Question

Helpp i need the surface area , hard to see the numbers but they are 18 and 15

Answer 1

Explanation:

Easy...

a=.5bh

so, .5*18*15= 135 in^2.

It looks like it has about four triangular sides, so just multiply that number four times.

135*4= 540

add the base

a=lw

=15*15

=225

540+225= 765 in^2

Let's hope. A better photo next time would definitely help....;)
