Consider one pyramid
Side length of base = 1.5cm and its height is 1 cm
Slant height of one of the lateral faces = sqrt(1^2 + 0.75^2) = 1.25 cm
Area of one of the triangular faces = 0.5 * 1.5* 1.25 = 0.9375 cm^2
There are 8 of these so the required surface area = 8 * 0.9375
= 7.5 cm^2 Answer
Answer:
Step-by-step explanation:
Spilt 5 into 3 parts (equal) and shade 2 of those parts
Well if you make it to slope intercept it would be y=-1/2x-2 so you start at -2y at 0x and it goes down one for every time it goes over two
Straight line angled up to the right intersecting the y axis at y=-7/3
