A prism has a volume of 160 cubic units.

Lerok [7]

The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. Then after multiplying the base and height get that answer and put the units in whatever it says too. Like if base is 7 inches and height is 12 inches you would put 84 in squared( 84 in ^2). Cubic units is like 160 in ^3( 160 inches cubed)

Paraphin [41]

Answer: a) $\frac{175}{100}xy\\\\=1.75xy\\\\$

b) By 0.75 square meters the new area is increased.

Step-by-step explanation:

Let the length of room be l

Let the breadth of room be 'b'

As we know the formula for "Area of rectangle ":

$Area=Length\times breadth\\\\Area=l\times b$

Now, According to question, The new area of the room is 175% of the previous area.

So, a) New area of the room becomes,

$\frac{175}{100}xy\\\\=1.75xy\\\\$

So, it means Length of the room is increased by 175%, because of which the area is increased by 175%.

b) By how many square meters has the area of Megan's room increased

$1.75xy-1xy=0.75\\\\\text{So, by 0.75 square meters the new area is increased.}$

I think the answer is 34. Because 106 - 13 =93 and 3 goes into 93, 31 times. And then you add 3 to 31 to get 34.
