Surface area of larger box is 69% more so as a scale factor that is 1.69
Square root 1.69 = 1.3
Height of smaller box x 1.3 is height of larger box.
18 x 1.3 = 23.4 cm
Height = 23.4 cm
Step-by-step explanation:
A. 3x+4/2 = 9.5
3x + 4/2 = 9.5........criss cross
3x+4= 9.5×2
3x = 19-4
3x = 15
x=5 ..........divide both sides by 3
B. 7+ 2x/3= 5.......criss cross
7+2x = 5 × 3
7 + 2x = 15
2x = 15-7
2x = 8......divide both sides by 2
x = 4
