Question

The figure below is made of two sizes of rectangular prisms one type of prism measures 3 inches by 6 inches by 14 inches. The other type measures 15 inches by 5 inches by 10 inches. What is the total volume of this figure

Answer 1

The complete question in the attached figure

we know that
[volume of a prism]=L*W*H

first type of prism measures 3 inches by 6 inches by 14 inches
then
[volume first type of a prism ]=3*6*14----------> 252 in³

second type of prism measures 15 inches by 5 inches by 10 inches
then
[volume second type of a prism ]=15*5*10----------> 750 in³

[volume of the figure]=2*[volume first type of a prism ]+[volume second type of a prism ]

[volume of the figure]=2*252+750---------> 1254 in³

the answer is 1254 in³
