Jules reads that 1 pint is equivalent to 0.473 liters. He asks his teacher how many liters there are in a pint. His teacher resp
andrey2020 [161]

One pint is equivalent to 0.473 liters which is approximately 0.47 liters if rounding off nearest to hundredth decimal places and 0.5 liters if rounding off nearest to tenth places.

Further explanation:

Jules reads that one pint is equivalent to 0.473 liters.

1\,\,{\text{Pint}}=0.473\,\,{\text{liters}}

But according to his teacher, one pint is about 0.47 liters.

1\,\,{\text{Pint}}\approx0.47\,\,{\text{liters}}

His teacher round off a value of one pint in liters nearest to hundredth places.

Also according to his parents, one pint is about 0.5 liters.

1\,\,{\text{Pint}}\approx0.5\,\,{\text{liters}}

His parents round off the value of one pint in liters nearest to tenth place.

Therefore, his parents and teachers are both right approximately.

Thus, one pint is equivalent to 0.473 liters which is approximately 0.47 liters if rounding off nearest to hundredth decimal places and 0.5 liters if rounding off nearest to tenth places.

Answer:

\large\boxed{Surface\ Area=63\ cm^2}

Step-by-step explanation:

We have

square  with sides <em>s = 3cm</em>

four triangles with base <em>b = 3cm</em> and height <em>h = 9cm</em>.

The formula of an area of a square:

A_\square=s^2

The formula of an area of a triangle:

A_\triangle=\dfrac{bh}{2}

Substitute:

A_\square=3^2=9\ cm^2\\\\A_\triangle=\dfrac{(3)(9)}{2}=\dfrac{27}{2}=13.5\ cm^2

The Surface Area:

S.A.=A_\square+4A_\triangle\\\\S.A.=9+4(13.5)=9+54=63\ cm^2
