Answer 1

Mark me as a Brainliest pls

Step-by-step explanation:

Given : -

• l = 7 units
• b = 6 units
• h = 8 units

Solution :-

We know that

The surface area of cuboid = 2(lb + bh + lh)

=> The surface area of cuboid =

$2(16 \times 15 + 15 \times 8.5 + 8.5 \times 16) \\ = > 2(240 + 127.5 + 136) \\ = > 2(503.5) \\ = > 1007 {cm}^{3}$

Conclusion :-

Therefore , the surface area of the cuboid whose l is 16cm, b is 15cm and h is 8.5cm is 1007cm³

Answer 2

Answer is 1007

Step-by-step explanation:

Explanation

formula to find surface area

2{(l×b)+(l×h)+(b×h)}

substitute

2{(16×15)+(16×8.5)+(15×8.5)}

2{(240)+(136)+(127.5)

2(503.5)

1007
