he diagonal of a cuboid is 25cm, breadth is 16cm and height is 12 cm. Find its length, volume and surface area

Answer»

ANSWER:

length=15, volume=2880

Step-by-step EXPLANATION:

DIAGNOL of CUBOID =√l²+b²+h²

25=√16²+12²+x²

squaring on both sides

625=256+144+x²

625-256-144=x²

225=x²

√225=x

15=x

volume of cuboid=l×b×h

Answer»

Answer:

800

Step-by-step EXPLANATION:

LET the TOTAL MARKS be x

ATQ,

86.875℅ of x = 695

86.875x/100= 695

86875x/100000 = 695

x = 695 * 100000

__________

86875

x = 695 * 4000

______

3475

x= 695 * 800

________

695

x = 800

thus , total marks is 800

47.	1/4√28 find the rationalization denominator
Answer» Answer: Step-by-step EXPLANATION: $\frac{1}{4\sqrt{28} }$ = $\frac{1}{4\sqrt{28} }$ × $\frac{4\sqrt{28} }{4\sqrt{28} }$ $\frac{14\sqrt{28} }{4^{2} (\sqrt{28} )^{2} \\} }$ the SQUARE root and the square gets cancelled = $\frac{4\sqrt{28} }{<klux>16</klux>(28)\\} }$ (now we've GOT to multiply 28 with 16) = $\frac{4\sqrt{28} }{448}$ ( the 4 and 448 gets cancelled ) = $\frac{\sqrt{28} }{<klux>112</klux>}$ if more simplification needed $\frac{\sqrt{28} }{112}$ ( $\sqrt{28}$ can also be written as $\sqrt{4 7}$ ) = $\frac{\sqrt{4 * 7} }{112}$ = $\frac{2\sqrt{7} }{112}$ ( 2 and 112 gets cancelled) = $\frac{\sqrt{7} }{56}$ Thank you for taking time and reading the answer Hope it was helpful :)

1/4√28 find the rationalization denominator

Answer»

Answer:

Step-by-step EXPLANATION:

$\frac{1}{4\sqrt{28} }$

= $\frac{1}{4\sqrt{28} }$ × $\frac{4\sqrt{28} }{4\sqrt{28} }$

$\frac{1*4\sqrt{28} }{4^{2} (\sqrt{28} )^{2} \\} }$ the SQUARE root and the square gets cancelled

= $\frac{4\sqrt{28} }{<klux>16</klux>(28)\\} }$ (now we've GOT to multiply 28 with 16)

= $\frac{4\sqrt{28} }{448}$ ( the 4 and 448 gets cancelled )

= $\frac{\sqrt{28} }{<klux>112</klux>}$

if more simplification needed

$\frac{\sqrt{28} }{112}$ ( $\sqrt{28}$ can also be written as $\sqrt{4 * 7}$ )

= $\frac{\sqrt{4 * 7} }{112}$

= $\frac{2\sqrt{7} }{112}$ ( 2 and 112 gets cancelled)

= $\frac{\sqrt{7} }{56}$

Thank you for taking time and reading the answer

Hope it was helpful :)

Answer» Answer: as we know that (a+b)^2 = a^2 + 2ab + b^2 now LET a = 40 and b = 2 substitute the values, =>(40+2)^2 = (40)^2 + 2×40×2 + (2)^ =>(42)^2 = 1600 + 160 + 4 =>(42)^2 = 1764 THEREFORE the SQUARE root of 42 is 1765 HOPE IT HELPS:)

Answer:

as we know that (a+b)^2 = a^2 + 2ab + b^2

now LET a = 40

and b = 2

substitute the values,

=>(40+2)^2 = (40)^2 + 2×40×2 + (2)^

=>(42)^2 = 1600 + 160 + 4

=>(42)^2 = 1764

THEREFORE the SQUARE root of 42 is 1765
