Answer:

14 cubic units

Step-by-step explanation:

The Formula for Volume is

V = L x W x H

Since there are 2, you need to add the two totals together.

Cubic one:

4 x 1 x 2 Β = Β 8 (it also doesn't matter what order you put your numbers in, you will still get the same outcome. Its called the commutative property of multiplication)

Cubic Two:

1 x 3 x 2 = 6

Now just add the totals together:

6 + 8 = 14

Answer:

  • A) 14 cubic units

Solution:

Here, we have to find the volume of the solid which is made up of two cuboid. We know that the volume of cuboid is given by:

  • V = l Γ— w Γ— h

The volume of the solid will be equal to the sum of volume of given two cuboid

For 1st cuboid :

  • l = 4 unit
  • h = 1 unit
  • w = 2 unit

Therefore, Volume:

➝ V = l Γ— w Γ— h

➝ V = 4 Γ— 2 Γ— 1

➝ V = 8 unit³

For 2nd cuboid:

  • l = 1 unit
  • w = 2 units
  • h = 3 units

Therefore, Volume:

➝ V = l Γ— w Γ— h

➝ V = 1 Γ— 2 Γ— 3

➝ V = 6 unit ³

Now, Volume of solid :

β€Žγ…€β€Žγ…€β€Žγ…€βž™ 14 unit Β³
