Ayuda con mi tarea de matemáticas , dice asi : En una biblioteca hay 5 estantes , 2/5 de uno de ellos está ocupado por libros de
laiz [17]

There are 5 shelves in the bookcase.

2/5 of one shelve is occupied.

That would be:

2/5*1/5=2/25 of all shelves

7/2 is more than 1, so it refers to the bookcase instead of one shelve. The same with 11/10.

So the total is:

2/5+7/2+11/10 = 5

So all shelves are completely full.

So there is no room for any other book.

Find the surface of this triangular prism please
Daniel [21]

Answer:

270cm²

Step-by-step explanation:

The formula is given as

S = bh × l (s1 + s2 + h)

l = 7cm

h = 5cm

s1 = 12 cm

s2 = 13cm

b = 12 cm

Surface Area = 12 cm × 5 cm × 7 cm(12 cm+ 13 cm+ 5cm)

= 60cm² × 7 cm(30 cm)

= 60cm² + 210 cm²

= 270 cm²
