Question

1. stephan is building a structure out of cubic blocks. he needs to add two more cubic blocks. what will be the volume, in cubic blocks, of stephans completed structure? a 16 cubic blocks b. 22 cubic blocks c. 24 cubic blocks d. 30 cubic blocks 61. which figure has a volume of 12 cm³?

Explanation:

Step1: Count the existing blocks

Count the number of cubic blocks in the initial structure. Let's assume there are 28 blocks (by counting rows and columns, for example, if it's a \(5\times6\) grid - like structure with some missing, but after proper counting without the 2 additional ones).

Step2: Add the required blocks

Since he needs to add 2 more blocks. The formula for the total volume \(V\) (in terms of number of cubic - blocks) is \(V=\text{existing blocks}+\text{added blocks}\). So \(V = 28+ 2=30\)

Answer:

D. 30 cubic blocks
