Question

find the volume of a cuboid with dimensions 3p,( 7p -2q) and ( 2p + q+r). calculate the volume if p = -1,q=1 and r =0​

Answer 1

Answer:

-27 unit .cube

Step-by-step explanation:

p= -1 , q=1, r=0

One Side=3p = -3

Second Side = (7p - 2q) = (-7 -2) = -9

Third Side = ( 2p + q + r) = (-2 + 1 + 0) = -1

Volume = LBH

Volume = -3 * -9 * -1

Volume = -27 unit .cube

Answer 2

$\sf{Solution}$

Step-by-step-explanation:-

Given :-

Dimensions of cubiod

• 3p = length
• 7p-2q= breadth
• 2p+q+r = height

Values of p,q,r

• p = -1
• q = 1
• r =0

To find :-

Volume of cuboid

Formula implemented:-

Volume of cuboid = length × breadth × height

Explanation:-

Given three dimensions of cuboid but indirectly they given interms of p,q,r but they given values So, for finding dimensions substuite values of p,q,r in dimensions

Hence we will get 3 dimensions. We can find volume

So, Lets do!

Solution :-

Length = 3p

p= -1

Length = -3

Breadth = 7p-2q

p = -1

q = 1

Breadth = 7(-1) -2 (1)

Breadth = -7-2

Breadth = -9

Height = 2p+q+r

p = -1

q = 1

r = 0

Height = 2(-1) + 1 + 0

Height = -2 + 1

Height = -1

Finding volume

Volume = l × b × h

Volume = -3 ×-9 ×-1

Volume = -27unit³

But volume can't be negative

So, volume of cube is

27unit³
