Scientific notation : 7.88 × 105
Use the Pythagorean Theorem to check out these possibilities (which you really do need to share here).
Note that 13^2 = 12^2 + 5^2, so 12 and 5 are a possible set of side lengths here.
Answer:
Step-by-step explanation:
Surface area of the facing side and its opposite side = 4* height = 4 * 2
= 8 m^2
Total surface area = 2 * 8 + 2 * 4 *4 + 2 * 4 * 2.5.
= 16 + 32 + 20
= 68 m^2.
Without a picture, it would be three linear pairs but to be more exact I would need a picture
hope this helps
