Question

PLEASE HELP, THE ANSWER I PUT IS WRONG

Answer 1

Data:
length=5 m
width=3.5 m
height=75 cm=0.75 m

Surface area of a rectangular prism=2(length x width)+2(length x height)+2(width x height)

Surface area=2(5 m*3.5 m)+2(5 m * 0.75 m)+2(3.5 m * 0.75 m)=
=35 m²+7.5 m²+5.25 m²=47.75 m²

Answer: 47.75 m²

Answer 2

Data:
lenght=5 m
width=3.5 m
heigth=75 cm=0.75 m

Surface area of a rectangular prim=2(lenght x width)+2(lenght x height)+2(width x height)

Surface area=2(5 m*3.5 m)+2(5 m * 0.75 m)+2(3.5 m * 0.75 m)=
=35 m²+7.5 m²+5.25 m²=47.75 m²

Answer: 47.75 m²
