A

## DETAILS…

The ratio of the length of two similar rectangular blocks is 2:3. If the volume of the larger block is 351cm³, then the volume of the other block is 234cm³, let me explain…

Let the length of block1 = 2L

The length of block2 will be = 3L

Let the breadth of block1 = B

The breadth of block2 will automatically be = B (because they are similar in breadth and width).

Let the width of block1 = W

The width of block2 will automatically be = W (because they are similar in breadth and width).

Recall that the volume of a rectangle = Length × Breadth × Width

Volume of block 1 will be = 2L × B × W= 2LBW

Volume of block 2 will be = 3L × B × W = 3LBW

But from the question, volume of the larger block = 351cm³, this implies:

3LBW = 351

LBW = 351/3

LBW = 117

If LBW = 117, this means

Volume of block1 = 2LBW = 2 × 117 = 234cm³

### Now for the right answer to the above question:

1. Option A is correct.
2. Option B is not correct.
3. C is not correct.
4. D is not the correct answer.
