Question

sandeep has cubic wooden blocks of height 8 inches.pankaj has the blocks of 12inches.how many of each would each of them need to build an equal height structure

Answer 1

Thank you for asking this question. Here is your answer:

The options for this question are missing, here are the missing options:

A) 4

B) 8

C) 12

D) 24

Answer:

The correct answer is 24 and the reason for this is that we will take out the LCM  of 12 and 8 in order to solve this question and the LCM of 12 and 8 are 24.

So the final answer for this question is Option D: 24

Answer 2

Answer:

Sandeep need 3 blocks and Pankaj need 2 blocks to build an equal height structure.

Step-by-step explanation:

Given: Height / edge length of Sandeep's Cubic wooden block = 8 inches

           Height / edge length of Pankaj's Cubic wooden block = 12 inches

To find: No block each required to build an equal height structure.

First we find LCM of 8 & 12 as LCM gives equal height of structure obtained.

8 = 2 × 2 × 2

12 = 2 × 2 × 3

LCM = 2 × 2 × 2 × 3 = 24

⇒ Height of Structure = 24 inches

No of cubic blocks Sandeep need = $\frac{24}{8}=3$

No of Cubic block Pankaj need = $\frac{24}{12}=2$

Therefore, Sandeep need 3 blocks and Pankaj need 2 blocks to build an equal height structure.
