For question 2, the answer is 120 cm^2
The formula is SA = b + 1/2 ps
p = perimeter
s = slant height
this is a square, so all the sides are equal. So 6 cm x 4 = 24 cm, this is the perimeter of the base.
then multiply this by the slant height, and you get 192.
192 x 1/2 = 96.
96 + 24 (the area of the base) = 120.
120 = 24 + (1/2 x 24 x 8)
If this is a cube and each side is 6ft, each face will have an area of 6ft * 6ft, or 36ft. There are 6 faces on a cube, so 36ft * 6 = 216ft² as the surface area (it's also the same as 6³, fancy huh?)
Answer:
Find the equation of the line perpendicular to x = 0 that passes through (-3,1)
Step-by-step explanation:
Using the equation, y - y1 = m(x - x1)
Since x = 0, the gradient, m = 0
Hence, y - 1 = 0
∴ y = 1
