Sagot :
Answer:
SA = 76 cm²
Step-by-step explanation:
Surface Area (SA) of a cuboid: 2(lw) + 2(wh) + 2(hl)
SA = 2(lw) + 2(wh) + 2(hl)
- l = 4 cm
- w = 2 cm
- h = 5 cm
Substitute the values above and multiply:
SA = 2(lw) + 2(wh) + 2(hl)
SA = 2(4)(2) + 2(2)(5) + 2(5)(4)
SA = 2(8) + 2(10) + 2(20)
SA = 16 + 20 + 40
SA = 76 cm²
Final answer: 76 cm²
