Answer:
Step-by-step explanation:
The given options are
A. 8 (one-half (24) (5))
B. 8 (one-half (24) (13))
C. (24) (24) + 8 (one-half (24) (5))
D. (24) (24) + 8 (one-half (24) (13))
We, should know that, the base area is covered and it cannot be seen, so the shape does not have a physical base area.
Then,
We need to find the area of the 8 sides triangle that formed the pyramid
Area of a triangle is ½base × height
But for a pyramid the height is the slant height
Then, the eight triangles are identical
Then, the area of the eight triangles is
A = 8 × ½ base × slant height
From the diagram,
The base length is 24cm
And the slant height is 13cm
Then,
A = 8 × ½ b × l
A = 8 × one-half × 24 × 13
A = 8(one-half)(24)(13) cm²
So, the correct answer is B
Numeral value
A = 8 × ½ × 24 × 13
A = 1248 cm²
