A Paper weight has the shape of a regular triangular pyramid find the surface area of the paperweight put the answer in Square meters Will Mark brainlest if correct

Step-by-step explanation:

area of a triangular pyramid = base area + 3(triangular sides area)

                                              = 1/2 (5) 4.3  +  3 (1/2 x 5 x 8)

                                              = 10.75 + 3(20)

                                              = 70.75 in²

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :
