250 boxes

Step-by-step explanation:

Volume of a cuboid = (length × breadth × height)

Bigger cuboid

Length = 30cm

Breadth = 50cm

Height = 20cm

Volume of bigger cuboid = (30×50×20)

Volume =30 000cm^3

Smaller cuboid

Length = 3cm

Breadth = 10cm

Height = 4cm

Volume of smaller cuboid = (3×10×4)

Volume = 120 cm^3

No of small boxes needed to fill bigger box =

30000/120

= 250 smaller boxes

I hope it helps :)

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
