Answer:

156 cm³

Step-by-step explanation:

The volume of any prism is the product of the base area and the height of the prism. Here, we can take the "base" to be the front face of the assembly, and its "height" to be the 3 cm distance between the front and back faces.

The front face area is the sum of the triangle area and the rectangle area.

A = 1/2bh + LW

A = (1/2)(10 cm)(4 cm) + (16 cm)(2 cm) = 52 cm²

Then the volume is ...

V = Bh = (52 cm²)(3 cm) = 156 cm³ . . . . total volume of the two blocks

Omar has 2-5/8 cups of dough to make dumplings. If he uses 3/16 cup of dough for each dumpling, how many whole dumplings can Oma

Arte-miy333 [17]

Answer:

The number of whole dumpling does Omar make is 14 .

Step-by-step explanation:

Given as :

The number of cups does Omar has to make dumplings = x = 2 $\dfrac{5}{8}$

i.e x = $\dfrac{16 + 5}{8}$

or, x = $\dfrac{21}{8}$

Again

The number of cups uses for each dumpling = y = $\dfrac{3}{16}$

i.e y = $\dfrac{3}{16}$

Let The number of whole dumpling does Omar make = z

So, number of whole dumpling does Omar make = $\dfrac{\textrm number of cups does Omar has to make dumplings}{number of cups uses for each dumpling }$
