O d. none of these​

Answer 1

Answer:

(a) 236cm²

Step-by-step explanation:

Size of cuboid = 8cm x 6cm x 5cm

total surface area = 2(LH + HB + BL) = 2[(8X6) + (6X5) +(5X8)]

                                                              = 2(48 + 30 + 40)

                                                              = 2(118) = 236cm² (a)
