Two similar building blocks have masses of 2.7 kg and 800 grams. The surface area of the smaller block is 120 cm². Find the surface area of the larger block.

Here are the solutions to the problems you provided:

7. Enlargement
The problem provides the coordinates of the image points P'(4,6) and Q'(7,3) after an enlargement. However, the coordinates of the original points P and Q are missing. Without the original points, it is not possible to calculate the scale factor or the coordinates of the center of enlargement.

8. Similar Building Blocks
The masses of two similar building blocks are 2.7 kg and 800 grams respectively. Find the surface area of the larger block if the surface area of the smaller block is 120cm².

Step 1: Convert the masses to the same units.
Mass of larger block ($M_L$) = 2.7
