01. Solution:- the length of the given cuboid=2a
the breadth of the given cuboid= 3a^2
the height of the given cuboid= 6a^4
so the volume of the cuboid= (length x breadth x height)=(2a x 3a^2 x 6a^4)= 36a^7

q2. Solution: given that the value of x= 4 so, the value of the expression:- 3x(2x+7)+25= 3x4(2x4-7)+25= 12(1)+25= 12+25= 37

Q1 ans 36a⁷
Q2 ans 37
Mam I really like so much your classes thank you for teaching this concept.

[archanahebbar-cw]

hello mam, homework question answer: 10 volume of a cuboid= l*b*h
2a*3a2*6a4 = 36a^7 thats the answer
2) once we solve the expression, we get= 6x2 - 21x + 25
now, we will replace x with 4 in both the LHS and the RHS
so, we get
6(4)^2 - 21(4) + 25 = 3*4*2*4-7+25
96-84+25= 12+25
12+25 = 12+25
37 = 37 LHS=RHS
Hence, 37 is the answer
Thanks!

Homework question
Ans 1 - volume of cuboid = l x b x h = 2a x 3a^2 x 6a^4
= 36a^7

Ans 2 - 3x (2x - 7 ) + 25
(3x x 2x) + (3x x( -7)) + 25
6x^2 - 21x + 25

For value = 4
6(4^2) -21(4) + 25
96 - 84 + 25
= 37

Q1. Volume = (length) x (breadth) x (height)
Given:
Length = 2a
Breadth = 3a²
Height = 6a^4
Substituting the given values into the equation:
Volume = (2a) x (3a²) x (6a^4)
Simplifying the expression:
Volume = 36a^7
Therefore, the volume of the cuboid is volume = 36a^7 cubic units.

Q2. 3×4(2×4-7)+25
12(1)+25
12×1+25
Ans: 37

I have been looking for study videos everywhere but this is the only one which I understood from. Thank you ma’am 😊

[jyotidevi]

Mam I watch your all video I only understand from your videos.I want my maths teacher like you

[AmritaKaur-mrxn]

Answer 1: Volume of cuboid = l × b × h
= 2a × 3a^2 × 6a^4
= 2 × 3 × 6 + (a × a^2 × a^4)
= 36a^7

Answer 2: 3x(2x - 7) + 25
= 6x^2 − 21x + 25
= 6(4)^2 - 21(4) + 25
= 96 - 84 + 25
= 37

Q1. Volume = (length) x (breadth) x (height)
Given:
Length = 2a
Breadth = 3a²
Height = 6a^4
Substituting the given values into the equation:
Volume = (2a) x (3a²) x (6a^4)
Simplifying the expression:
Volume = 36a^7
Therefore, the volume of the cuboid is volume = 36a^7 cubic units.
