How can you use base ten blocks to find 1.54 + 2.37

alekssr [168]

We can use 100s for ones place, 10s for tenth place and 1s for hundredth place.

Addition of 4 and 7 in the hundredth places will give 11.

Replace 10 blocks with 1 tens block.

Add this 1 to 5 and 3 which are in tens place. This will be 1+5+3 = 9.

Addition of 1 and 2 in ones places 3.

Hence, the answer is 3.91.

What is the surface area of the solid figure represented by the net?

Ivenika [448]

Answer:

Option B. 373.80 square centimeters

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The surface area of the figure is equal to the area of its 5 faces (3 rectangular faces plus 2 triangular faces)

step 1

Find the area of its 3 rectangular faces

$A_1=(5.6)(9.4)=52.64\ cm^2$

$A_2=(12.7)(9.4)=119.38\ cm^2$

$A_3=(13.9)(9.4)=130.66\ cm^2$

step 2

Find the area of its 2 triangular faces

$A_4=\frac{1}{2}(12.7)(5.6)=35.56\ cm^2$

$A_5=\frac{1}{2}(12.7)(5.6)=35.56\ cm^2$

step 3

Find out the surface area

$SA=A_1+A_2+A_3+A_4+A_5$

substitute the values

$SA=52.64+119.38+130.66+35.56+35.56$

$SA=373.80\ cm^2$
