The number of small cubes in each cuboid is:
(a) 3, b) 6, c) 27, and d) 16.
Given are four cuboids.
It is required to find the number of small cubes that are used to make these cuboids.
a) There are only 3 small cubes.
b) There is only one step of cubes.
Number of cubes = 3 + 3 = 6
c) There are 3 cubes arranged horizontally and 3 cubes arranged vertically through each surface.
Number of cubes in one step = 3 × 3 = 9
There are 3 steps like that.
So, total number of cubes = 3 × 9 = 27
d) There are 4 cubes in the horizontal position.
And there are 4 cubes going down.
Total number of cubes = 4 × 4 = 16

The lengths of the two boards (234 inches and 246 inches) and adding them together, we find that the combined length of the boards is 480 inches.
To find the total length of the two boards, you need to add their individual lengths together.
Step 1: Identify the length of each board. The first board is 234 inches long, and the second board is 246 inches long.
Step 2: Add the lengths of the boards together.
234 (length of first board) + 246 (length of second board) = 480
So, the total length of the two boards on the shelf is 480 inches. This means that if you were to place the two boards end-to-end, they would cover a distance of 480 inches.
In summary, by identifying the lengths of the two boards (234 inches and 246 inches) and adding them together, we find that the combined length of the boards is 480 inches. This calculation helps us understand the total amount of space the boards would occupy if placed side by side.
