Step-by-step explanation:
Given data
breadth=9 in
Length=11 in
Now a square of side x is cutted for each corner such that the cardboard is made into a open-top box with
length=11-2x
breadth=9-2x
height=x
Here substract 2x because from both sides of length and breadth x units are reduced.
therefore volume of new open-top box is
Volume(v)=
Answer:
6 in
Step-by-step explanation:
The <em>area</em> of a picture <em>is</em> 25 7/5 square inches. If the width of the picture is 4 1/2 inches, what is the length? <em>(A=(w)(l) </em>)
Assuming that your "25 7/5 square inches" is not a mistake, then this is equivalent to 26 2/5 square inches.
Converting 26 2/5 sq. in. to an improper fraction, we get 132/5 sq. in., which represents the area of the picture. If the width is 4 1/2 inches, or 9/2 inches, then the length, l, is:
132/5 in^2
l = ------------------
9/2 in
To divide 132/5 in^2 by the fraction 9/2 in, invert 9/2 and multiply:
135 in^2 2
l = -------------- * ------ = 270/9 in = 30/5 in = 6 in

Answer:
Solution given:
length [l]=20cm
breadth [b]=10cm
area of rectangle =l×b=20×10=200cm²
since 1cm=1000cm
than real area =200×1000²=200000000cm²
since
1 hectares =10000m²=10000×10000=100000000cm²
so
200000000cm²=2hectares
So,actual area of the piece of land in hectares is 2 hectares.
Answer:
Answer:
Volume of cylinder =πr²h=π×4²×5=80π m³
=251.2m³
Volume of cuboid=l*b*h=7*3*2=42in³
Volume of cone =(⅓πr²h)+(⅓πr²h)⅓π×(6/2)²(12+8)=60πft³=188.4ft³
