Yes, I can certainly help you
The dimensions are
5x , 3x and 2x ( since 5:3:2 is just a ratio , its lowest term)
so
5x * 3x* 2x = 3750
30x³ = 3750
x³ = 125
x = 5
Hence the dimensions are : 25 , 15 and 10
Total surface area = 2( lb + bh + hl)
= 2 ( 375 + 150 + 250)
= 2(775)
= 1550 cm^2

Heya
_____________________________
Let the common ratio of length , breadth and height is
5x : 3x : 2x
=>
Volume of cuboid = ( 5×3×2×x³)
=>
30x³ = 3750
x³ = 125
x = 5cm
So, Length , breadth and height is
5×5 = 25cm , 3×5 =15cm And 2×5=10cm
it's surface is =
2 { (25×15) + (15× 10) + (10× 25) } cm²
=
2 { 375 + 150 + 250 }cm²
=
2{ 775 } cm²
=
1550cm²☺️☺️☺️
