Question

the volume of rectangular block of candle wax is 375 cubic cm it has a length of 20cm and width of 7.5 cm what is its height​

Answer 1

Answer:

Volume of rectangular block = L× B× H

L= length

B= width

H= height

Step-by-step explanation:

A/q

L×B×H = 375cm³

20 × 7.5 × H = 375 cm³

H = 375/ 150

H= 2.5 cm

Height of rectangular block= 2.5 cm

Answer 2

Height of rectangular block is 2.5 cm.

Given:

• The volume of rectangular block of candle wax is 375 cubic cm.
• It has a length of 20cm and width of 7.5 cm.

To find:

• What is its height ?

Solution:

Formula to be used:

Volume of cuboid:$\bf V = l \times b \times h$

here,

l: length

b: breadth

and h: height

Step 1:

Rectangular block is a cuboid.

Volume of block (V) = 375 cc

Length(l)= 20 cm

breadth/width(b) = 7.5 cm

Step 2:

Put all values in the formula.

$375 = 20 \times 7.5 \times h$

or

$h = \frac{375}{20 \times 7.5}$

or

$h = \frac{3750}{20 \times 75}$

or

$h = \frac{5}{2}$

or

$\bf h = 2.5 \: cm$

Thus,

Height of rectangular block is 2.5 cm.
