Question

Please help me rq!! i need help

Answer 1

Answer:

x = 2

Step-by-step explanation:

The volume (V) of a cuboid is calculated as

V = lbh ( l is length, b is breadth, h is height )

Here l = 10x , b = $\frac{7}{4}$ , h = 2 , then

V = 10x × $\frac{7}{4}$ × 2 = 70 , that is

20x × $\frac{7}{4}$ = 70

5x × 7 = 70

35x = 70 ( divide both sides by 35 )

x = 2

Answer 2

Answer:

$x=2$

Step-by-step explanation:

Since L × W × H = V, we get

$10x*\frac{7}{4}*2=70\\10x*\frac{7}{4}=35\\10x=20\\x=2$
