33 part a is h=30 so a=15 and I think it would be 121 cm2 for the area
33 part b is just the first base which is 12
33 part c is 176.4 is the length

Answer:
The value of K is 5
Step-by-step explanation:
I reversed it.
The tiny squares means 90⁰, so 90+49=139
All of these angles add up to 180⁰
So 180-139=41
The k equation equals 41⁰, so reverse it to find answer
41-1=40
40÷8=5

Answer:
1090 in²
Step-by-step explanation:
The surface area of the two cube = 7x7x6 + 13x13x6 = 1308 in²
But noted that there are overlapping of the two cubes, thus we need to minus 7x7 in² from the answer. Also, we need to minus 13x13 from the answer as the bottom face of the larger prism do not require staining.
∴The required surface area is 1090 in²
