Sagot :
Since area is Length x width x hight all we need to do here is multiply 3 x 5 x 2. Let’s start with 5 x 2 that equals to 10. Then we multiply 10 x 3 which is 30! Hope this helped!!
Answer:
62 cm²
Step-by-step explanation:
The surface area is the sum of the areas of the 6 faces
The opposite faces of the cuboid are congruent , then
SA = area of front/ back + area of top/ bottom + area of side faces
SA = 2(5 × 3) + 2(5 × 2) + 2(2 × 3)
= 2(15) + 2(10) + 2(6)
= 30 + 20 + 12
= 62 cm²
