Question

A solid metal bar is in the shape of a cuboid
of length 250 cm and volume 4840 cm3. The
Cross-section is a square of side x cm. Find x.​

Answer 1

Step-by-step explanation:

length of the bar 250 cm

volume of the cuboid = 4840 cm3

cross section is square of X *X, so volume is

$v = lbh \\ 4840= 250 \times x \times x \\ {x}^{2} = \frac{4840}{250} \\ {x}^{2} = 19.36 \\ x = \sqrt{19.36} \\ x = 4.4cm$

side of the cross section is 4.4 X 4.4 cm
