Answer:
144cm²
Explanation:
Area of a triangle = 1/2 x base x height
6 x 8 = 48 / 2 = 24 cm² (area of the frontal side)
24 x 2 = 48 cm² (this is for both equal sides, so it is not necessary to multiply by 2)
The top side area:
Since it is a rectangle,
10 x 4 = 40cm²
Bottom side area:
8 x 4 = 32cm²
Back side area:
6 x 4 = 24cm²
40 + 32 + 48 = 120 cm² + 24 = 144 cm²
