Question

Find the surface area PLEASE HELP! will mark brainiest Thank you :)

Answer 1

Answer:

12796 cm²

Step-by-step explanation:

$SA=2(lw+lh+wh)$ where l is the length, w is the width and h is the height

Plug in 42 as l, 35 as w and 64 as h

$SA=2(42*35+42*64+35*64)\\SA=2(1470+2688+2240)\\SA=2(6398)\\SA=12796$

Therefore, the surface area of the figure is 12796 cm².

I hope this helps!

Answer 2

Answer:

Solution :-

TSA = 2(lb + bh + lh)

TSA = 2(64 × 42 + 42 × 35 + 64 × 35)

TSA = 2(6398)

TSA = 12796 cu. cm
