icang [17]

Answer:

the answer b

Step-by-step explanation:

[surface area]=[area of 4 triangles sides]+[area of square base]

[area of one triangles side]=24*20/2--------> 240 cm²

[area of 4 triangles sides]=4*240----------> 960 cm²

[surface area]=[960]+[576]--------> 1536 cm²

2(4x - 1) + 3(3 - 2x) = 0
LUCKY_DIMON [66]
2(4x-1) + 3(3-2x)=0
